It isnt homebuilt, wasnt sure where to post this sorry.
I have looked around and found http://www.cyberpowersystem.co.uk as a decent site to build cheap custom pcs for people in the uk.
i have the link to what i have built and wanted advice on any changes you think are worth it.
My ideal build will be a computer with three screens.
The best i7 processor i can get and a decent motherboard (doesnt have to be amazing).
However issues i had with my last computer with overheating which i dont want to have with this so I think i have chosen a decent number of fans and a liquid cooling system. Wasnt sure if you had any advice for me there.
I also want to run dual video cards, an nvidia gforce 670 and the recently bought graphics card for my old pc which is an nvidia geforce 560 ti. Not really sure if this will work mixing these two together or if the motherboard supports two at all. Would be great if you could help and sorry this is very garbled.
