Thanks again!
I wonder why the Mac Minis are so popular then? I guess maybe for those who don’t have iMacs.
Besides the reasons given, relatively low cost (for an i7) and very small footprint, the mac mini still compares favorably in terms of power consumption, which actually does add up in terms of real money for a computer left on 24/7.

Crash0veride, thanks for the detailed response!
One last question for someone. I have 4 8TB WD external drives. I was thinking of using the first 2 for media, and the second 2 as backups for the first 2. Can my iMac or do this or should I go with some type of NAS?
Technically, yes. I believe raid software is still supported (back to being supported?) in mac osx. In this case you would stripe two drives, then mirror those drives (striped as well?)
a better raid software solution is softraid, pricey but data is precious so probably worth it..

But having played around with various software options in my tower mac pro, i ultimately went with a synology NAS. Just seemed cleaner.
On second thought maybe you don't mean raid at all (where all those drives essentially appear as one volume) but 2 drives on your desktop with two being mirrored. Um. yeah could still do that but ugg. messy. I like simplicity. Its a matter of what you are willing to juggle. and i think for media its just easier to manage one virtual drive then several physical drives.
