If anyone is wondering, the screws for the top metal cover are quick release screws. Just a 1/2 turn and they pop up. Makes it easy to take off. The video card marked "bad" is actually good, it was repaired before being put back in. The repair is on the backside of the card. Likewise with the blown capacitor. I replaced that one myself.
The motherboard is otherwise a stock IIfx motherboard. The power supply is a bit different. Has that nifty large master switch on it.
