Looking for some suggested builds as will soon be building my own as a project, it will be used for a lot of gaming and multi-tasking with a range of programs, haven't really got a budget at the moment but really don't want to be spending any more than 800GBP but would be willing to stretch it for something worthwhile. Just looking for the tower, no monitor or mouse or keyboard.

And I don't mind from what site as long as they are a UK site like Overclockers.

Thanks
