I built this in April but I have been too busy to show you guys. I haven't overclocked anything yet, partly because I haven't had time and partly because I haven't really pushed the limit of anything yet. BF3 runs like a dream!
I got some pretty good prices on some parts for the time. I think memory is probably the best buy out of the bunch compared to todays prices. The particular memory I bought is currently £63 from the same place I bought it!
Corsair have kindly sent me a H100i/H80i cable accessory kit for free to allow me to hook up my case fans to the Corsair Link software!
I am currently running Windows 7 Professional N (64-bit), which I got for free through my university's DreamSpark subscription. I could get Windows 8 but I don't really see major benefits over 7.
