On ebay there are some $100 hp and dell blade server units that I've seen in action in data center tours. My question is, would a single one with 32gb ram, 4 intel xeon 3ghz processors and NO graphics card be able to run ubuntu? And would ubuntu be able to actually use the entire system? I won't be using it for "big data" per se, but I am thinking of compiling my own custom android builds and building/compiling my own custom build of ubuntu (kind of just for the fun of it, maybe a little for the fact that I'll be able to show off computer prowess). Also, I want to know if a full desktop environment would even run right due to the lack of a graphics card. I might be able to get a graphics card, but if I can avoid it I will at all costs (except for if it exceeds the price of a card).
