Box Only Build - Need some input

[EZShot]

Hi guys,

In the market for some components as my box had seen it's last easy upgrade a year ago.

Basically just want the box, no peripherals, no monitor and also NO graphics card. I already have a lowly hd5450 and this will do fine untill I've got another £200 and can afford something worthwhile. This is on a budget of £400 although I could probably stretch an extra £50 or so.

List:

Case
Mobo
CPU
RAM
PSU
DVDDrive
HDD

Don't have any preference in the components manufacturers just want the best I can get.

Have already spent a good few hours trawling the net but as I haven't built one in some time the market has moved on and I'm a bit outta the loop.

It will be used for Adobe CS4 Suite, Ableton & Gaming (eventually)

Thanks, Alf

EDIT: Should be noted that I enjoy a PC with minimal noise. So if you can factor in a good quiet cpu cooler for the money that would be awesome
