After many weeks of planning and hunting around for the best/cheapest components I finally put my brothers rig together:
Core i5 750 - £141.44
MSI GD80 - £85.50
4Gb G.Skill 1600MHz CL9 - £66.99
Asus 4870 512Mb Dark Knight - £91.45
Corsair HX450 - £52.20
Antec 300 - £43.97 (plus 2 x coolermaster blue led fans £10.21)
Samsung Spinpoint F3 500Gb - £34.49
Samsung SH-S223B/BEBE - £15.16
Windows 7 Pro 64bit
Currently have the processor set at 3.2 using the XMP profile. When i'm not working/learning i'll get and give it a proper stress test before handing it over. Well impressed with windows 7 taking 15 mins to completely install so things are looking good!
Any thoughts on potential overclocking/tweaking? Didn't find the OC genie that good as it wouldn't run the memory at 1600MHz, but it did give a fairly decent overclock (think it was around 3.4)
