The Power Supply
The next obstacle to overcome was the ATX power supply. Thankfully, the PSU fit just fine into the opening, but the AC outlet opening didn't *exactly* line up with the opening on the chassis. This wasn't too terribly important, of course, since the cable would still go in. One could debate extending the hole in the PSU's metal cage so that the outlet would move into the proper position, but the idea of desoldering the socket, cutting open the power supply, and resoldering the outlet, didn't exactly appeal to me, especially since the issue was relatively trivial. The fan grille was also blocking the PSU from moving any further, and I wasn't going to be able to make a satisfactory modification to that.
The PSU opening
It should definitely be noted that if you should wish to pursue this project yourself, there are several different models of the G4 chassis that have been used over the years, one of the major differences being that some have a differently-shaped opening for the power supply. If you try to get one of these cases yourself, make sure that it's either the right one, or that you can return it if it's not.
