Build a DX10 rig for under £176

Likewise, if you want a 1Kw PSU that supports the likes of SLI, then it's going to cost a fair amount of cash. At the other end of the spectrum is the all-in-one case and PSU deal. We found one for just £26, which includes a 400W PSU.

This may not sound like a lot of power, but it's more than enough to run our setup. When spending such a small amount of money on a case, you'd expect it to be quite horrific, but it's surprisingly well featured. It has a matt-black finish, which helps on the looks front, and the front panel has USB and audio ports.
