Yes but I'll have to see what other drives I can fit in there. It
would no doubt save some power.  I must look at how many headers are
left on the motherboard. It already has two sata and two ide drives in
there (one IDE is a dvd drive). I know there are no more sata ports.
There is a spare PCIe slot which I assume could house a sata card.

If I wasn't such a magpie with media files I might have enough room....
