And probably a 24" Samsung TV as a monitor, though I haven't properly looked at them yet.
And I believe I will need a couple of SATA cables.
Cheap mouse and keyboard.
I'm aware that currently there is no graphics card in this set-up and that if I wanted it to be able to play any half demanding game it would probably fall over. However, I do have a Radeon 5770 in another machine that I may upgrade soon. So in the back of my mind I'm thinking I can put that in this build at a later date if I feel I need to. (if the case will take it :\ may have to upgrade the PSU and it might be a bit of a squeeze.)
Any advice would be greatly appreciated. I'm a bit of a novice so if I have made any stupid mistakes please don't hesitate to correct me!
