Quick update, ordered all of the parts except for the case, DVD drive and power supply. This was because I visited a local store today which is run by my mate's elder brother, he agreed to put the system togethor and throw in a case, drive and power supply he had at the store for only £50.
Plus they will test it, install all the drivers and OS and even polish it for me.
I will let you guys know how it goes. Cheers!
