I am building a PC, and have got a £500 budget for the PC alone (not the peripherals). Could you please tell me if this build will work, and if not which parts? Could you also recommend some changes I could make, as long as it stays under the £500 mark. Here's the link for my build http://uk.pcpartpicker.com/p/sPtKrH , (I am aware I dont have an OS or peripherals, I am buying them elsewhere).
