so what I did was mount the SSD into the bracket with the screws, then simply double sided foam taped the _bracket_ into the MP's 2nd optical bay area... and ran a cable from on of the spare mobo connectors. given that the thing weighs a couple oz's and doesn't make much heat I think this works fine and still leaves the main 4 drive holes open for large capacity spinning disks

I'd also put this out  - doing a clean OS install is fairly painless. Migration assistant will pull over every thing once this is done. However, if you have had several CS installs you'll probably want to go on a global search and destroy mission ( include System Files )  as I found 20g+ ( 14,000 files ) of leftovers from installs going back to CS3. given the limited capacity of SSD's no need to keep all this junk... and yes I've spoken to "the right people" about a clean up util / script that does a better job of removing all this old stuff and I think its on the radar. however it is really nice to have a clean installed machine.using DMG's of all the installers helps a huge amount instead of DVD's for cutting the time down. It took me 4-5 hrs which was pretty good compared to previous installs.
