I just replaced my cheap, crappy old AMD 690 micro-ATX board with the Asus M3A32-MVP Deluxe AMD 790FX, since I was able to buy it from the previous owner for cheap.
I've spent most of the day taking the system apart and re-assembling it again. I hit a lot of snags along the way, for example the screwholes didn't align with the mobo because of the thick IO shield Asus shipped with the board. I had to physically bend the rear of the case outwards slightly... Also had to take the harddrives out and then squeeze them in once the board was in place...a tight fit but that's what you get when you go with the cheapest case.
I'm always amazed when a system boots up for the first time and actually displays an image on the monitor. I dunno..I always expect either just a black screen, or flames, smoke and explosions
Initial test run:
Got a new cooler and tidied up the inside a bit.
