Okay this is going to sound a bit strange, mostly because the inquiry is more home construction / IT related, but it is for my music room... I am moving my home office / music room into a larger room, with a larger / walk in closet. The closet is large enough I am going to move my IT equipment into the closet using a 20u rack, and rack mount it all, with the exception of a docking station, KVM cable into the closet, and of course keyboard, mouse, and monitor. I have already tested to see if it works, and yes, my Behringer USB Audio Interface does work to record via my cluster to a VM. (Using oVirt cluster to get the job done). Latency, as far as I can tell, is no different than going into my laptop, so what the heck, go for it right? So anyway, I am going to have 5 PCs, a RAID enclosure, 2 16 port, 1 24 port switches, an 8 port KVM, WiFi router, VoIP adapter, printer, and cable modem in this closet... How the heck do I get AC into the closet, and get the hot air out?
