I am going to be building a custom pc that i want to be fast, upgradeable, and able to last me awhile. I am mainly going to be using it for gaming, word processing, and some video editing (just smaller stuff for youtube). My questions really is does the case size of mini, micro, mid or full tower ATX really matter? I want to be able to bring it to college, and so if i do get a bigger case, i want carrying handles. any suggestions?
