ha ha, yup, generally white of black but you can have different designs also, but prices can vary wildly on case. Cases can come with/without fans also, so can make a big difference overall to price. Both myself and
@MissChief have put builds to maximise your performance over looks, while still putting good quality cases in builds.. Id there something more specific you had in mind...if going white build, then other things to look at would be white ram, mobo with white accents etc...there's generally a 'white' tax to pay though, unless there's a promotion for white at time of buying
