Boy Howdy! Got me stumped. I am out of time to research this but some other brands that come to mind and I looked at are: Chieftec, Antec, Powmax (I did try to find pictures of older case in these brands), Logisys, and Gigabyte.
The 5.25 quick lock cut-outs looked to me very much like the Rosewill cases I have worked in: And though I looked for Antec cases, the locking system is similar to an older case from them that I once had.
It looks like a decent case: If it is relatively sturdy, none of the front panel wires frayed-shorted-broken, and the price is acceptable I would just buy it, clean it up and build into it. Looks like it has plenty of locations for fans and certainly more-then-enough drive bays.
