As for storage space if it helps, for the 576 CDS that are stored on a drive, only using about 43 megs for them. Looking at a 300 gig drive for the HTPC for now and will see if we run out of space soon.
I may have the new toy assembled and online in a few weeks, but also could be longer since I need to get the racks installed. So you could order and have yours in and be done before me.
