I'm with jacob on this one. You do get what you pay for. My power supply died in this machine about 15 minutes ago. This was because I was using a crappy one that came with a cheap case. Knowing that this would happen, I got a new one before this happened so I could replace it when it did. Now all my problems on this pc are fixed. Easy. Also with ram. I was working on a graphite iMac yesterday at work and OS X kept kernal panicing. I unplugged it flipped her over, and opened up the airport/ram door to find the stock 128mb stick and a cheap generic 128 meg stick. I replace the generic one and didnt have any other problems with it.
