I wont be buying it till June and i know the whole technology constantly fluctuates in prices stuff but i was having some difficulty thinking about it. It needs a monitor aswell, 22", cant afford anything more and dont have the space for anything more. The case i've settled on a BitFenix raider because its only £60 on ebuyer and has some nice features. It doesnt need an optical drive (not that any one uses them anyway but in case some one did). No preference for GPUs. It wont be doing anything other than gaming and watching stuff on the internet.
