I'm looking for something like the Rosewill RSV-L4500 but not exactly.
I would like an affordable case that has 3x3x5.25" bays that will fit 5-in-3 hot swap cages like the Norco SS-500. I'm honestly not even sure if the above case can fit any, if it only has bays for mounting internal 3.5" drives. It's kind of hard to tell from the pictures whether those internal bays can be removed or modified to store something like the SS-500.
I also would like something that's not quite as long as that case. It's 25" long plus the handles. It seems at least 3" longer than necessary to hold a regular ATX board and something like the Norco SS-500 in front of it. But if the RSV-L4500 will work then I can't complain too much.
You might ask, why don't I just save up and get something like the NORCO RPC-4020? I have a couple reasons... first of all it's also super long so it's not quite ideal. The second reason is I have had a bad experience with 2 of the 2 of these I have ever worked with. One of them, drives would not stay connected when multiple drives were being written at once. It seemed like the vibration would knock them out. The other one, my friend had and the top lid became warped and stuck. He had to cut it open with an angle grinder. Maybe we were just unlucky? Also, I can imagine having 15 drives in a case but in all likelihood I will never have more than 12, maybe even 10. I'm starting with 5. A case that could grow to hold 3 cages with 5 drives each would be ideal. I would use one for now, and possibly add a second or third cage later.
You might also ask, if I had bad experience with Norco before, why would I buy their 5 in 3 cages? I have no idea...maybe I shouldn't, but they seem pretty well regarded here.
