This whole thing is confusing me *My plan was to keep the original tray and just put the SSD in some kind of adapter, which would be held by the original tray. Is there such a thing? I see lots of plastic junk out there, I don't think I'm interested in that. I've also seen OWC's tray, but like I said, I don't know if I really want to replace the tray. They say their tray is blue, so we remember in which slots we got our SSDs. Alriiight Also, in Bay 1 I have a 2TB HDD. Is it okay to place the SSD in Bay 3 or 4 for security reasons, because of heat from the HDD for example? I don't like the idea of everything being in one corner, and 2 bays will be left empty for now anyway.
