3700X & 3900X Productivity/Gaming PCs: $1088 & $1348 + Delivery @ TechFast


Hi folks,

Hitting an all-time low price for a 3900X productivity machine, with Biostar X570 GTA motherboard, 16GB 3000MHz RAM, 240GB 2.5" SSD for those bringing their own or upgradeable via the site, 650W 80+ Bronze PSU, starting with a Biostar RX 550 4GB GPU upwards.

Also offering a 3700X productivity machine with B450, 16GB 3000MHz RAM, 240GB SSD, RX 550 upwards, and 750W power supply.

Both come in the new Leaper Air Maxx case, which should meet the majority of community feedback we have received over time regarding our cases. It's been a long time coming due to various minor complications like a global pandemic, but it is a full mesh-fronted ATX case with 3 x 120mm RGB fans (RGB functionality can be turned off while fans keep spinning), 240mm radiator support, full length tempered glass side panel, PSU shroud and support for 2 x 2.5" and 2 x 3.5" drives.

  • Any hope of a 4700G build anytime soon? I am disgruntled with it being OEM only but hopefully you guys can do something about it.

  • Other July deals ending soon

    ending in July perhaps ?

      Perhaps, but some will run for a few days. They're not on auto expire

      • If the special is still going I will be keen to purchase a 3700X by Monday. Just have a question on the B450 motherboard. How many memory slots does it have ?

  • Buy a 3700X and become immediately more productive

    • I think you're being sarcastic, but it's actually true. I have a 4th gen i3 without even an ssd at work. As an example one task I had to do maybe 4-20 times per day was compiling the project which would take 10+ minutes. At home I can do the same task in under 5 minutes, and I have a budget computer…

      • Serious question. What kind of workplace gives you a workstation without an ssd in 2021?!

        • Here we all are wondering what else 2020 can throw at us and this guy is living it up in 2021.

          At least we know one person survived this year.

        • Hospitals. At least the few I've worked at, they've all been using outdated pieces of shit.
          Admittedly at the same hospitals, all connection is via virtual connection so the computer does nothing more than act as a display. But the virtual server is so slow that it might as well not be SSD…

    • Not with three fancy RGB case fans, you won't be. Get back to work!

    The $260 price difference to get the 3900X system seems like a no brainer since you get the X570 board and the much better PSU. Sell the RX550 and drop in a GPU of your choice and you've got a serious machine for the money.

    • I agree. This seems like a great setup for the money!

    • Would it make sense to get the 3900X bundle now and then wait for the new Nvidia graphics cards?
      Currently using a 1070 so the RX 550 would be swapped/sold.

      • Yep unless you want to wait for ryzen gen 4, I think that would be a good way to go (chuck the 1070 in it and use it until RTX 3000 series comes out).

  • $130 more for a wifi Mobo?

  • In no rush to get a new rig, is now a good time or should I wait till later in the year? component prices gonna drop?

  • I have the 2700x and tempted by this. is this case heavy?

    • The tempered glass definitely adds weight. Its the same weight as the MAG Forge, about 5.5kg without components.

  • Hey Luke,
    I've been a long time lurker of your posts just waiting for the day to either build or purchase a gaming computer and was wondering if you do custom builds?
    Reason being is I've got my own ram lying around so wanted to save costs where I can.

  • Hey Luke,
    Just wondering if you could shed some light on what RX550 is used?
    Also the dimensions if possible?

  • Many "productivity" machines I see are plenty powerful for gaming

    • Ryzen is good for mixed workload/gaming. I'd up the ram to skew it more towards productivity.

      Go Intel if gaming is your priority.

      • Go Intel if gaming is your priority.

        Not necessarily… if you haven't got a top of the line GPU in your part list you could drop the Intel CPU and Z-series board necessary for overclocking to a Ryzen and B-series board, then you can afford a better GPU which will improve game performance more than the Intel CPU could.

    • The RX 550 isn't going to be gaming.

  • With the 3700X build, is there any chance you could add an option for a b450 motherboard from another brand such as MSI or Gigabyte (perhaps one such as https://www.pccasegear.com/products/50001/msi-b450-gaming-pr... ) which will be slightly pricier than the biostar but not quite as much as the b550 option?
    Also I'm curious about the PSU, as there's nothing specified for the generic 750W, however the gold certified 750W is significantly more. Any clarification on that?

    Thanks in advance

    • We don't have any other B450 options at the moment - the B450 Mortar was there previously but is unavailable, others have not been available in sufficient quantities prior to that. The Mortar B450 may return when it comes back into stock.

      The base 750 is a simple cost effective unit with a substantially lower price than 750W Gold units, which have also jumped in price due to shortage and demand of late, hence quite a large delta. The Bronze is a good option for those seeking a rated unit.

  • Hi Luke

    Is it cheaper to purchase it disassembled (parts only) or its the same price .. just takes longer cause you have to put it together ??


    • Lol they will never seller it disassembled, how would they test it? Since they warranty the system. Better option is just source the parts yourself and build, if it was more expensive won't be much

    • Hi, yes, we do offer it unassembled. Our assembled warranty does not apply so individual manufacturer's part warranties apply to each component. We can assist with this if required in the event of a faulty component. Enter SHIP UNASSEMBLED in the Notes field at Checkout to request it. It does not generally save much time as orders are picked on the same day.

  • Luke, what is the approximate date to receive the 3900x system if I were to buy, its says in stock but I've heard on previous deals people have complained of delays.

    • Every system is estimated 14 business days from order to dispatch and we do our best to be as close to this as possible. It is an estimate not a fixed time, due to the nature of the Australian supply chain environment.
