This is a high quality Antec computer mid tower server case. It has a locking side panel. There are eleven drive bays, with quick release drive bay cages. There are front audio and USB ports. I’m including a rear 120mm tricool (3 speeds) fan. An optional one can be installed into the front as well, just behind the front removable washable dust filter. The case is 19x19x8-1/2in. Make a fair price offer to purchase. Delivery negotiable.
