All I want to do is record HDMI with Blackmagic Intensity Pro, I need to build a small desktop that can be by my TV, what are the bare minimums for this? The editing will be on another PC, my wife just won't let me keep it by the TV since it's huge. So I just want to build something small that can hold that PVR and doesn't have to do anything else but store video and transfer it to an external HDD. Any advice? I want this as cheap as I can go.
