The OptiBay installation took me all of 5 minutes. It comes in a bundle with the correct screwdriver(s), if you don't have a Torx T6. Mine also came with an external enclosure for the superdrive. The actual installation is very simple, mostly removing screws; only one ribbon cable is a little delicate, but not a problem either. If you have any experience tinkering with electronics, it's a breeze, but if you don't, just be a little careful, not much can go wrong. Or, of course, have someone do it for it. I didn't plan on reselling this computer ever, but if I were, I assume that the buyer would be just as happy with more HDD space and a super-fast system disk, plus an external SuperDrive. Worst case I could always build this back to stock configuration within half an hour.
