That Case/PSU isn't as i orgionally spec'd - will that power supply still work? (It's my little treat - taking me over budget :S)
The Motherboard - does that come with built-in graphics (If so, can i still fit the Palit 9500 GT?) Sorry, the info on the e-buyer website is a bit naff.
All in all - im pretty happy with this spec - any advice or thoughts would be great.
