I built a system along the lines of what you are looking for. Basically its a 24-7 download machine and file sharer.
Mine is.
The Intel® Desktop Board D945GCLF (atom based all in one board)
Venus 669 case (good because it can hold multiple hard drives and has a 5.25 inch slot. Also it has a good 200w power supply included)
1gb ram
1x2.5 250gb western digital green power
1x3.5 750 gb western digital green power
1 PCI gigabit ethernet card.
The system was chosen to be the lowest powered that was reasonably attainable at the time. It draws about 50W in load.
I would recommend two hardrives for a download machine. One hardrive will be the "downloader". This is my 2.5 inch. Its constantly active writing the torrent chunks. The other harddrive should be your "final" hardrive. In this case the "downloader" when finishing a torrent will move the file to the "final". It is the "final" that is shared on the network.
I use azureus running under XP on the torrent machine. I control the downloads from another PC using the azureus remote control plug in AzSMRC. In this case I dont need a monitor or keyboard connected to the torrent machine. For all other connectivity issues I use VNC to control the torrent PC.
I have been running it now for about 6 months, without problem.
