You guys might be right about the power supply, but I'll just see how it goes for now - it did get good reviews online anyway. I actually had an Antec I was going to use, but I plugged it in and it was dead and smelled like burnt electronics, so I guess even good brands aren't always reliable. The one I bought is an Ultra "X-Finity."

The board did fit fine to the Dell case. I was a little afraid I was going to have to hack up the case fan shroud but it turns out I didn't have to. I did have to change around the pins in the connector for the power switch, HDD light, and power light to get those to work. Front usb ports plugged right in and worked. The front audio port has some special connector-I don't know if I am going to get it to work. Not worried about it right now.
