Large ATX computer case with space for way too many hard drives(like 10?). PSU(not included) mounts at the bottom and has a filtered air inlet(removable filter). Font door opens to reveal 3 5.25" slots(2 blanks included). Top front sets of USB2 and USB3 ports. Sides and door are a sandwich of materials to deaden sound and its very quiet(was used in my former recording studio) with 3 large low RPM fans. Some drive sleds are missing screws(2 complete sleds with screws are still in plastic). Minor scuffs and marks on the sides. Fits full sized ATX motherboards. I deal in cash and in person only, thanks. Text Dave between 10am and 7pm only to 8six0-33fore-fore77zero
