These are the things i'd like to have as spares for my cube to keep it going forever. DC/DC board Power supply brick Power Switch Spare fluorescent tubes for Lcd display maybe a case and for sure two or three cd-dvd internal drives the processor no because if i upgrade i'll have the old one and also the same with video card I think in the future these things might be hard to come by if you really need them. Well thats my wish list but it will never happen but a guy can dream can't he.
