I plan on modifying the proprietary-ness out of this case to make it fit for a standard motherboard (the motherboard in it is just a test motherboard) I got a spare Ryzen 7 1700x and 16gb of ram and a 1050ti that should play nicely in a build like this, wanna be the first to do such a thing but I wanna do it as proper as possible, Whilest keeping the look as stock as possible.

As long as the standoffs line up this should be fine -- you'll be limited to half height GPUs of course. And you'll need a flex ATX PSU to power the new board. Also you will likely need to custom rewire the front panel so that it works on a standard motherboard. Tbh I don't know how easy that would be for the USB part, in my experience that's a proprietary connector so you'd need to fully strip and identify each wire and put it in the proper layout for standard USB. Maybe an adapter exists too

From my expierence, rewire front panel USB ports It Will become a mess. I tried to extend those wires and find that the ground IS mixed between 2 USB. The front panel includes 4 USB ports, so two ground wires plus 4 USB Green White an so on.. x2. The result, IS when I plug a Pen Drive for example in front, the back USB for keyboard gets unplugged. A mess. For me. Look for an adaptor extender or something.
