Slightly better i5 for cheaper at Aria
http://www.aria.co.uk/SuperSpecials/...roductId=40924
I`m thinking of getting one of these
https://www.aria.co.uk/Products/Comp...roductId=40619 but will only need a CPU, memory and maybe a graphics card so may well be asking similar things soon
Still can`t believe i only paid £45 for Windows 7 HP and £80 for Pro (retail versions), wish i`d had the forethought to buy half a dozen of each
Good luck with whatever you go for
