Hi
If you arnt happy building your own pc give the guys at
http://www.overclockers.co.uk/
a call,they can build you a pc to your requirements or will probably have something already for you to buy.
I have bought loads of stuff from them, they are cheap and know what they are doing.
To have a pc build by these guys costs very little more than buying all the items seperately.
Please what ever you do DONT go to PCWorld, they are a joke and will sell you any old crap to get you out the door.
