Well my step dad and I are working on getting a NAS system setup in the house. It will be running OnTap (NetApp software) and also have 2 of either a windows or linux pizza box (1U shelf). I am thinking if it is possible to run an SMP client on it without any issues. (OnTap which is the NAS OS is I am pretty sure is freeBSD or Debian). I know I wont be able to run the GPU client on it because there will be no screen attached to it since it will all be within the local network controlled on a GUI interface.
