The Corsair Graphite 730T is a budget version of the 760T which means you miss out on the polycarbonate side panel and don't get any fan controllers. Also, like a Model T Ford, the 730T only comes in black, whereas the 760T is available in black or white. On the plus side the 730T costs a reasonable £110, which is a good bit cheaper than the £147 you pay for the 760T.
