I'm dumb, what is a unit case? (I just responded to see if I could be the first to respond.. and I want to know what a unit case is)
Cool, nice lot of linkage there, ive been looking for rack stuff too, had only found kustom before... Heres some racks tho http://www.amblestreet.co.uk/foris/microcom_aaccs_cab.asp?offset=50
Oh, and btw. The u refers to the height of the case. 1U = the shortest then 2U, 3U 4U etc. until higher numbers which typically are only used in reference to the height of a rack cabinet.
