Doctor have a look up for a palce called bowlers computer fair it's located in manchester. I got my pc from there which im delighted with. Don't worry it's nothign dodgy like a mix and match cheap parts garage sale it's a well organized group of stores both who have perminent stores and soem who coem and go from tiem to time. There you could probably get the system you asked for under the 1K mark. The stores also normaly offer atleast some form of warranty I got a one eyar one with my pc but others offer 3 years or even mroe if your willing to play extra. You can basicly mic and match on aprts say buy a rig from one store then the monitor cheaper from another or buy a barebone system and buy your chosen graphicis card and so on. Also ask aroudn to fidn whos sellign the software you need windows Xp ect. It's very cheap for software aswell but personly I wouldn't buy any software other than windows Xp from there. Rembember one of the more memorable stalls selling a disk entitled "hackign stuff". :P
