Ok...I've search and searched and found a lot of information. I'd like to install a 100-128 GB SSD Drive into my 27" i5 iMac while keeping the 1 TB Drive that's already in there. It looks like I'll have to replace my superdrive and put the SSD in that slot. I'm confident I can do this myself, I just need to know what SSD drive I should use, and what adapters / brackets I'll need. I would also like to use my superdrive as an external drive. Is this enclosure good: http://eshop.macsales.com/item/Other World Computing/VLSS9TOPTU2/ So...what hard drive should I use and what parts will I need. Thanks in advance!
