I would like to use the following components to build a Media Centre:
Intel E6300
Gigabyte GA 965G-DS3
400GB SATAII
GeIL 2x1GB 800MHz Dual Channel
NEC 8x DVD±RW Dual Layer Slimline
Hauppauge WinTV-Nova-T-500 MCE/Dual
The real question is how much power do you think that lot will use unoverclocked and overclocked?

If you want to buy separate then look at a Silverstone Media Case with a Corsair 520W PSU. That aside though, that machine is way over-specced for a media centre PC- a cheap AM2 or 939 setup would be fine and save you a lot of money in the process 

i saw those reports but mine is running fine atm, had it since like october and should be good for a while longer (touch wood)
