First post, be gentle ;)
I was looking for this Corsair 120mm AIO and found the cheapest price right now was on Amazon AU. I think it's the cheapest I have seen it before. In my opinion, Amazon's fulfillment operations are very well optimised and any time I have ordered from the site it comes faster than the provided estimated delivery date.
I plan to use a Noctua NF-A12x25 PWM fan with this instead of the 120mm fan it comes with. Plenty of good reviews on Youtube.
