Quad core ATI 4870 gaming machine !

I built this PC just over a year ago. It has AMD 2.8ghz quad core, ATI 4870 card and 4gb DDR3 ram and 500gb HDD. Added corsair cx600 v2 ATX PSU which cost £50 and has box and warranty still. I have added an external fan speed controller the GFX card. The system has been running cool without issue since built, im an occasional gamer so not stressed this system. Full sized case with huge 12inch side fan and LCD on front. Everything you will need plus I will include Windows 7 home premium if given £130. I will zero write the HDD and format with new copy of windows ready to go.
