Antec Sonata III computer case. Support standard ATX, microATX and mini-ITX. Extremely silent case! 9 drive bays, 2 front USB ports, and more. For full specs, see https://web.archive.org/web/20180317194100/http://store.antec.com/sonata-family/sonata-iii-500.html Case has been lightly used. A couple scratches on the side/top but otherwise everything is in good order. I can throw in a case fan and DVD-RW drive if you need them.
