I think I am going with this case:
I know it is a little heavy but I don't plan on moving it around to much.
Also, will the motherboard I picked support 45nm technology? Somebody said it will but I would have to flash the bios. I don't know if I feel comfortable doing that. What are some good boards that support 45nm?
One more thing, I am connected to the internet through a network using a router. Both machines are using Windows XP. Would a Vista machine work with a XP machine? The XP machine is connected to the router.
