I've got a comms room that will be running 13.8v bus for everything in the room, but I need a computer that will run on that power too. I'm looking for something like the EEE PC desktop version. It needs to have enough power to run a 5MHz Software Defined Radio at realtime speeds, so basically, core 2 duo at greater than 2GHz. Unfortunately, it might need to run windows, so it needs 4GB+ of ram, and a video card. I have an SSD for it, so SATA is a must. Any ideas? I'd like to keep power consumption to a minimum, since this will be running on a battery bank that's only 460Ah.
