Used SKB 6 Unit rackmount case. Has room for 6 full space devices.  I didn't use them all. I have left in 2 full unit shelves. One is vented, like new. The other is older, and has duct tape residue on it. I have also included two full unit spacers, and 1 half unit spacer. At one time I had a desktop computer in this. It took up 2 1/2 spaces, so this 1/2 unit was perfect.  I got many years of service from this case. All latches work. Paypal only.
