6U GPU Bitcoin Mining Rig Server Case - 6 Fans Pre-Installed - Cooling vents w/ Dropdown Fan Backplate for Easy Internal Access - 6 GPU Compatible, with 6 PCI-E 16x to 1x Risers (Ethereum, ETH, Zcash)

A very nice overall finish to the product and it is good at what it was designed to do. Relatively easy to build inside (probably what you would expect from such a massive case though) and has the ability to be modded a bit if the buyer is inclined as there is a back panel that could be changed to incorporate a pcie bracket (meaning potential for more cards!), I have seen these screw on pcie bracket panels available for server cases haven't spent the £20 to get one yet though. You can also easily route cables for a PSU from outside the case for a 2nd and might be able to move the support for the PSU around in such a way as to fit a 2nd, you can use two server PSUs no problem though.However this case does have a few design flaws I'll go over quickly. Firstly, the right angled power cable inside the case you use to attach to the PSU had the right angle facing towards the bottom of the case (Corsair RM 1000x) which made it quite difficult to fit it into the PSU due to the obstruction on the bottom, my cables just about in the back of the power supply now but it is at a slight angle.Secondly, at least one usb 3.0 port would have been nice to see rather than two 2.0Thirdly, it would have been nice to see a pcie bracket for the motherboard installed by the manufacturer rather than a screw on air vent (which is handy to be able to unscrew during installation). As I said these can be found online but is difficult and hard to know which will fit
