Try it same as in the above link (green text), except substitute the CPU and the Mobo parts with

CPU: Core i3 2100
Mobo: Asus P8H67-M PRO

Those two together will run you just under 200 pounds, but the videocard is integrated and you get like 3 video outs, so you save the money you'd otherwise put in a discrete card. Plus, you can simply drop in any other Sandy Bridge processor in it in the future when the price goes down for instant performance boost. That motherboard can hold up to 32GB (!) of RAM, so you will have a much easier time upgrading when the prices come down (and these parts start existing).
