I've been offered a 24" IMAC that has some issue with fusion drive for US$200, I mostly use my 5,1 macbook but it would be cool to have a 24" screen to work on photoshop. So I would like to know where to get a caddy to put a SSD instead of the superdrive, I've been looking on ebay but I'm not sure of what I'm doing, could anyone point to a caddy that would fit my needs please? Will any of these be ok? http://www.ebay.com/itm/2nd-Hard-Dr...7?pt=US_Drive_Bay_Caddies&hash=item416ee67785 http://www.ebay.com/itm/For-new-App...68?pt=LH_DefaultDomain_15&hash=item43c160f804 Also, is it possible to install OS on the SSD from my macbook so the imac would just work fine after I install the SSD? I want to format the original HDD for data. I really don't care about fusion drive, should I? Thanks.
