Just audio or in general?
My office closet is also a server closet, but all that is in use. There are also enough parts to build multiple PCs, but it's all older, working stuff.
I've got a box of speakers that were for my Cambridge Soundworks speaker system for my PC. Those and some from an old Kenwood 5.1 setup.
Got a set of old Pioneer towers in my garage with a KLH sub sitting on top. I thin there are some Aiwa speakers in there too back from highscool.
Got a 70" Vizio taking up space in my game room since it's slowly turning purple.
Got a bunch of unused AVRs too. My first one (Kenwood again) and my newer Pioneer 512 that was dirt cheap, but very good. There are a few subwoofer drivers under my HT riser that I should probably use with the plate amp that's sitting in a drawer.
I need to get rid of some stuff...
