Got my current PC for about £600 and it still runs really well. Probably only worth about half that now so you could easily get a bargain on one. Actually, I'm considering selling it in the next month or so if you'd be interested for about £350 ono? Spec is:
Antec 900 case (excellent condition with a couple of nicks/scratches)
DVD "multi recorder" (whatever that means)
Q6600 2.4GHz quad core processor
4GB OCZ RAM
8800GT 512MB graphics card
2x250GB Seagate Barracuda 7200rpm (I think) HDDs
OCZ StealthxStream psu
Could either supply with blank hard drives or legit version of Windows XP or maybe Windows 7 if uni will give me a different serial so I could do a fresh install..
I use that for all my uni work which involves audio recording/production, video editing and compositing, 3D modelling and animation, photoshop, then all the usual internet, music etc. Hasn't really had any problems at all. Coming to the end of uni now though and I really don't need all the power it has so its just a waste of electricity!
