Good luck! I have my own machine so I'm good. If I thought you had any clue what you were getting into I would be more supportive but clearly you do not. Just a tip: Airolib-ng is WAY to slow for this job. The only current way top do it in linux is with pyrit and cowpatty. See my tutorials for help on setting it up.
By the way those tesla box's are not servers. Each Tesla box has 2 cables with cards at the end which go in to PCI 16 slots only. You will still need one server for each of them and then cluster them to get the power of both. Unless you get 1 server with 4 pcie 16 slots. So make sure you add that to the price. You are looking at a good 22,000 dollars US. for all that crap.
