The Xion power supply isn't going to cut it. It's made by L&C, which is total garbage. Buy a case without a power supply or order a better power supply and change it out.

If you dont need a second cdrw drive, leave it out. Also the price differences between 120-200GB are about $20 max, so you could get more hd space for your dollar.

Don't think you need ECC RAM. Might look at some Corsair Value Select, or the non-ECC version of what you've got.
