Picked up a Lonovo m91p SFF box for the price of the Intel i7 2600 itself. Was looking to build a media server, but I have a larger case and PSU. Is there any reason why I shouldn't just re-case the M91p and install a GTX card to turn this into a budget gaming/media hybrid? Anyone know if there would be any limitations from the motherboard for what GTX chips I could work with?
