    Not buying but I'd use an i5-8600K and put the savings towards 2080 Ti. Ditch custom loop for CPU if necessary to get there.


      How is pairing both of those components suitable?


        because hyperthreading is useless compared to a better video card and 8600k will overclock to 5+ghz easier

        • +9 votes

          Hyperthreading on the 8700k vs 8600k does net an overall 30+% improvement on CPU intensive tasks.
          It's true that most previous generation games don't need more than 6 threads either, but more are coming out now with that ability. Plus live streaming and rendering can definitely make use of them.

        • +3 votes

          6c/6t ruins min framerates especially if the game uses all 6 cores as windows doesn't have anywhere to put background processes.

          the cum thermal interface material will continue to make these chips not hit their peak anyway, so it doesn't really matter.


      Even 8700k bottle necks 2080Ti at 1080p and 1440p..bad advice.


        Not if you overclock it - on a custom loop like this, it should be able to hit 5ghz easy? Delid and you'll have a rock solid 24x7 workhorse.

    • +2 votes

      Or save $1500 by buying the components separately.


      I would stick to the 8700k, better longevity. Software is starting to take advantage of more threads and 6 won't cut it long term.


      If u really want to cut costs for a ti you would lose the custom loop…. but it looks awesome!!!

  • +21 votes

    Looks fantastic, however for that price a 9700K and 32GB 3200mhz would make it a lot more appetising.

    • +1 vote

      I would order one today if they can match the above.

      • +5 votes

        For this particular machine in it's current spec, unfortunately that would mean I'd be at a loss even before taking into account shipping. The Valkyrie is likely only to break even at that price to be honest.

        I could however, match that spec and price if the cooling was changed to CPU only with a single 360mm radiator.
        9700k - Custom loop cooling + Overclock
        32GB 3200MHz
        RTX 2080 - air cooled
        500GB M.2
        2TB HDD
        750W PSU with custom sleeved CableMod cables
        Lian Li O11 Dynamic
        W10 Home
        Software controlled RGB Fans
        + 2 year Parts and Labour Warranty
        Total - $3,950 + Free shipping with discount code.

        The price can be lowered further if cooling is again switched for AIO, in which case I would recommend checking out our Crystal series configuration.

  • +9 votes

    You're putting some nice looking systems together, but for me, I can find the same parts at AU PC Part picker, but an AIO cooler instead, for 2900 plus change for the same parts, but not everyone likes putting their own systems together

    • +10 votes

      This is true, and our most popular machines are AIO based due to the added value for money. It's unfortunate that custom cooling parts come at the cost that they do, but for those who aim to show off you can't beat the looks.

      • +11 votes

        Yup - totally agree. If the systems look as nice as the pics then you're doing some fantastic work. And for those who value that crazy cool aesthetic, they should definitely get on this! If I was you, I would mention your custom cooling and design value a little more in your sales pitches - let people know where the value is in your products - it's not the parts it's the custom design of the cooling set up and the implementation. More pics etc too :D

        Of course you can ignore me, but I just thought it might help :D

      • +3 votes

        Do you have a link to your system which is $3000 with AIO please?

        Thanks :)

        • +2 votes

          Not identical, but very similar in spec with a Ryzen 2700X / i7 9700k in a compact dual chamber case by Corsair and 240mm AIO:
          Crystal RGB


        It's unfortunate that custom cooling parts come at the cost that they do

        So the cooling, cabling and lighting adds $970? What the hell are they made of?

          A lot of time and marginal profit.

        • +20 votes

          Cables don't comb and hide themselves, hard tubes don't cut and bend themselves, and the cooling loop don't fill and purge itself. All these tasks are labour intensive unlike the mostly plug-and-play nature of a normal DIY PC. You are paying for somebody else's expertise and time.

          ~$70 Fittings, angle adapters and extenders from Barrow

            @CCPC: Thanks. I can see now that it does all add up to quite a bit. Still seems totally insane to me though to not spend it on performance instead.

            I totally get that there are people out there that do want stuff just for showing off and you wouldn't be in business without them, but I doubt many of them are here. haha

          • +7 votes

            @CCPC: Great breakdown!! Kudos to you for transparency, I really appreciate this.

            However, like kamoi mentioned, that's almost a grand I could have spent on a seperate component upgrade, i.e bumping the GPU up.

            At least initially, for my first PC, I'm looking at getting something more performance-focused, and all this RGB bumping up the price sucks for me. :(

            I guess I'll just go for a cheap build and stick up a few of these RGB Strips.

            Thanks again for the breakdown, not a lot of retailers do that with pre-built PC's. Will definitely keep you guys in mind when I'm getting my PC and may ask for a custom quote for a more bare-bones PC, I'll bookmark your comment. :)

              @Zazer: Thanks for the kind words!

              We do mainly offer more value oriented AIO based machines, specialising in smaller footprint cases such as the Micro Tower for mid-range and Crystal RGB for higher end performance.

              And as you noted, we're happy to customise any order or build one from scratch to suit your specific needs in a case you like.

              Hope to hear from you in future :)

              [Edit]: Just noticed you had replied earlier to a different comment so this is partially a rehash of that one


                @CCPC: Yep, I had a peek at your site. Those PC's look great! There's definitely a few customisations I'd like to make though, so when I'm in the market for a PC soon I'll be sure to contact you guys! :)

                Just a quick question, how big is your operation? Haven't heard of you prior to today :)


                  @Zazer: Sounds great!

                  As you have probably seen we are still quite small, only having officially opened September of last year.
                  We're in the process of growing operations, streamlining the build processes and getting our name out in the wild.

                    @CCPC: Oh, okay! So only about 6 months old then.

                    I'll definitely keep an eye out for any mention of you guys, and will come back down the line when I'm getting a PC :)


            @CCPC: i had to do some googlefu to find that Barrow Distribution plate. well i found the bitspower version. seems like a pretty cool series of products. https://shop.bitspower.com/index.php?route=product/product&p...

            can you explain why you chose the non-NVMe version of the SSD? seems like an odd choice in an otherwise high end build.


              @antikythera: Sata based M.2 drives obviously help to lower cost, and in most OS and Gaming scenarios offer few, if any, noticeable differences.

              I find that NVME really shines for more work related tasks such as video editing.

              These are just recommendations though, and we are happy to accommodate special requests

    I’ve done a custom cpu and gpu water cool. It’s a lot of time to get it nice. Hard line would be especially more time consuming. More so as an unskilled DIYer.

    I am interested in upgrading well buying a whole new pc in about a years time hopefully when the 2080 Ti is more affordable.

    What is a good build similar to this one with max performance maybe 48gb of ram possibly 64gb.

    Will be carrying over 2 SSD's and 1 HDD from current build.

    The rest will be sold.

    Will need WiFi ac as well as Ethernet port.

    Already have a Windows 10 key and OS installed on my SSD so would just need everything but storage.

    Will be probably selling my current setup for around $1000 and putting it towards a 8700K/9700K/9900K RTX 2080Ti 64gb DDR4 setup.

    What can you guys recommend or price up?

    Don't need water cooling or fancy lighting just best performance cooling wise and low maintenance.

    Bonus points if the ports for usb devices can be at the front.


      I checked their website and they focus on the show off type of builds.

      • +1 vote

        Yeah damn looks to be that way.

        Ah well was hoping they would be my next seller as I am not very fond of pc building but assembling the part list I can do.

        It is what I did last time for my sff build and ended up paying my builder $150 for some nice personal touches and working with me so well and overall a very good job.

        The convenience and peace of mind is well worth it to know you get a good job done and everything adjusted to your specifications.


      Also interested in buying a max performance PC in about a year! Would also like best performance and low maintenance, let me know what you find please :)


        I will keep you posted if I find a good custom builder or just pc builder.

        Might try it myself but my guy says I shouldn't risk it.

        One mistake could cost hundreds and I usually stuff up or trip somewhere.



          Yeah, I'm keen to try myself but if I choose the wrong parts or push in the wrong spot, I could cost myself a lot :/

          Considering finding someone to help me make a build and then teach me to build it, not sure who though.


          As long as you watch some guides its pretty straight forward (dont watch the verge guide :P )
          watch a wide variety of guides on youtube from people like jaystwocents, pauls hardware, bitwits and even linus tech tips and you will pick up basically everything
          And if you come across any issues there are numerous forums out there on pc building filled with people that would be more than happy to help you.


            @Pyrock: I can get 80% of it but the remaining 20% will give me a headache.. trust me I have thought this through I am not a pc builder.

            Takes one wrong forceful jam and a pin gets bent or something gets mishandled and a capacitor gets broken then a whole bag of nightmares opens up trying to fix that or getting it rma'd or whatever.. Rather just pay the extra 50 bucks and get it done by a professional and peace of mind.

  • +1 vote

    would love to get this if i hadnt just ordered a whole computer worth of parts when CA had 20% off.

    You should do something about the waterloop going over the RAM though, seems like a difficult task if someone wants to add more ram in.

    anyways, great deal!

    • +4 votes

      Thanks for the kind words, Dogfight!
      With regards to the RAM, there is actually more than enough room to remove and install even quite tall memory under those pipes without dismantling any of the water cooling.

    For almost four grand, I would expect the 2080Ti rather than a standard 2080.

  • +2 votes

    Not sure it's a bargain, but I do appreciate the OP's transparency.

    Most other sellers wouldn't be even half as transparent.

    So kudos for that. I would rather a plainer looking PC with better GPU and CPU for less money - but hey, I drive a Hyundai not a Porsche.

    If you have the money and its what you want, why not. The price assembled with warranty and shipping isn't outrageously high based on the prices of the individual components.

    BTW - what are the precise warranty terms on this unit?
    Return to base at buyers cost = unclear
    How many years = 2
    Where is base = Brisbane area

    Does the Consumer Law apply whereby even if the seller states return to base warranty, the seller is legally obliged to pay the cost of shipping to/from under warranty??

    My concerns about liquid cooling is eventually it will leak - might be 1 month, might be 10 years, but it will happen - and when it does it could be catastrophic. Depending on the leak you could be looking at almost every major component being ruined.

    The chances of a custom cooling system leaking would arguably be higher than the chances of a quality closed loop off the shelf solution leaking too….

    My last 3 PC's (all still going) have off the shelf stock Corsair liquid cooling systems for CPU only. I figure as long as they last at least 4 years before leaking, the value of the computers will have depreciated so much, as well as their relative performance declining, that I won't care so much - still won't be a good day…

      Thankyou for your comments,

      With regards to the warranty we are currently offering 2 years parts and labour on all PCs, including to fix or replace any damaged parts caused by water leaks, or any corrosion in the loop assuming no alterations have been made by the customer. We leak test each custom loop quite thoroughly and will stand by it's safety for the full warranty period. However if the customer chooses to modify the loop, disassemble or change the coolant they do so at their own risk.

      Shipping of a repaired machine back to the customer will be our responsibility.

      Shipping from customer to base will be organized by the customer and later reimbursed if the PC is found to be faulty. In the case where the PC is too bulky or heavy to be easily moved by one person, or if evidence can be shown of a clear fault during the claim process we will assist in arranging a courier to collect it.

      As you mention we are located in Brisbane, but as we save running costs by not having a store front all transport is currently done via courier.

      I will make a note to clarify the website's refund policy if any of this is too ambiguous, and we of course have the full intention of complying with Australian Consumer Law as required.


    Also for that money I would have expected a hybrid HDD. They are not substantially more expensive but thye do deliver a good performance improvement on a standard 7200rpm HDD.

    Anyway I guess it's fully customisable so you get precisely what you want (for a price) which is a refreshing change from most of these high end system packages.

    • +3 votes

      Hybrids are out man. They don't make them any bigger than 2TB anymore and people have gone Intel Optane with bigger capacities for the same effect.

      Arguably with the price of SSDs dropping, you'd want a 2TB SSD more than a 2TB SSHD.


        Just picked up a 2gb ssd for ~$350 off this site. Negligible when it comes to a $4k PC.


        You can still get a 4TB discontinued Seagate SSHD - I actually hadn't realised they stopped making them over 2TB so thanks for the heads up.

        4TB discontinued model SSHD is $209 so its still a fair bit cheaper than a 2TB SSD.

        Agree SSD is better if your wallet can stretch to it. I'm pretty happy with my existing 4TB SSHD's running as storage in conjunction with 1TB SSD boot drive.

        And also agree Optane is good if you have enough M2 slots and a modern enough CPU/mobo to support it. It uses one slot, so it might not be the best option if you also have other M2 slot needs. 32gb Optane is about $110.

        The mobo in this build has 2 x M2 slots. One is being used by an M2 SSD…

        In this build a SSHD would be preferable to what they are giving you, a stock HDD. 32gb Optane would be even better albeit it the most expensive of the 3 options…

    Given the costs here, worth bearing in mind this is a new small business operated by a sole trader.

    ABN registered as operating under that business name in Brisbane since September 2018

    ABN was in existence since 2015 - started in WA - under no registered business name.
    It's not clear what business, if any, was operating under the ABN from 2015 to September 2018 when they moved it to Brisbane.

    You have to weigh up the chances of a small business folding. They are sadly pretty high.

    The components will have individual warranties, but they may not cover everything that could go wrong. For example if the cooling leaks, your motherboard warranty won't cover damage to the motherboard from the leak. Same applies to your CPU, hard disk, SSD, RAM, PSU and GPU.

    Because you are buying a fully assembled system, the individual component warranties may or may not apply at all - for example the video card manufacturer may well say that implementing the custom cooling solution voided the warranty on the GPU….

    If you bought a Dell Alienware or an ASUS ROG at least you would know your warranty was solid….

    But you'd pay more, and not get a system with these sort of looks or cooling designs…

    All businesses must start sometime of course, and these look good - plus the proprietor is open and transparent.

    But buyer beware…. Go in eyes wide open. I am not bagging the vendor, but people may not appreciate the risks…

    This is a lot of money for a lot of people, and it will end in tears if the business folds and you have an issue with any of the custom parts during the warranty period….

    Dude, that's some nice work.
    It's unfortunate many people don't realise the price of custom loop parts and are quick to jump down your throat.
    Will be in touch in the near future for a build
