Huh...I'll have a look. Mind you, it's not the quickest kid on the block now. The Barracuda in the old machine is noticeably quicker. And that's on 80 strand ribbon. It just makes a soft tearing noise with the case open. Silent otherwise. Rather impressive. Mind you, a younger person might hear it.
I've not checked on the spec of the WD drive yet. I've spent so much time getting the machine under control. (See Partition specific thread...if you're suffering from insomnia.)
