Me I just needed that USB Cable, Magnets and Arcade button + 80mm Fan, the rest I already had in my little workshop. Re-Used BeQuiet Silent Wings 4 Fans for CPU Cooler (BeQuiet PureRock 3LX) and front fans and got a new 80mm Noctua fan as exhaust. I'd suggest to re-do the MB tray as the current solution with the tray as four interconnected parts + 4 printed stand-offs towards the frame doesn't look all to sturdy to me, but depends on weight of CPU/Cooer/GPU combo.
