Change the case to an NZXT Beta or something else with a little... taste. PSU i'd go for the BeQuiet 650W that's £65 at the minute. Hard Drives have a look at WD Blacks or Samsung F3s.
Why 1156 and not AM3? Cheaper and very similar performance, with more upgrade potential in the future. Fans, i'd have gone with Apaches or something like that.
