Go on then, help me
Budget: £600-900
What I want - PC capable of playing CSS at 400fps all the time, Heavy Photoshop work and the occasional LAN event.
I'd prefer a mini-pc (similar to a shuttle XPC but without the massive cost)
what I'd like - i5, damn good GFX card, 560Ti or 6750 or similar, no HDD, no monitor 8Gb RAM)
Your goal, build me a PC for that cost.
Lowest cost that fits my description wins a prize (possibly cash, possibly something else)
GO!
Edit - <600 is better, but don't skimp on the things I'd like
