Cleaning up my own network

So my personal network closet started getting unmanageable.I began by removing the doors from the closet since they were trapping heat and I usually had to leave at least one of the doors open while operating the AV receiver or one of the PCs.

What my network started looking like after about a year.

The top shelf holds 2 phone systems (currently not connected) along with my 2500 phone, my patch panel, a turntable (currently not connected) and a Samsung HTIB (not connected) that will feed the audio for my zone 2 (bedroom). Also on this shelf are several ATA devices that are not currently used, mostly PAP2 devices, but also includes at least 1 3102 and several other generic ATA devices, eventually when I set up an asterisk server these devices will provide lines for the 2 phone systems.

The left side middle shelf holds my Brother all in one lazer printer.

The right side middle shelf holds my entertainment distribution center, centered around an Onkyo TX-NR626, it also includes my Roku3, a Samsung Bluray player, analog cassette deck Panasonic HTIB (which is only being used for its VHS player) an Xbox 360 (not currently connected) and an 8 port linksys switch.

On the bottom shelf lives 5 desktop computers (currently not connected) my Ooma, and an external laptop hard drive enclosure.

The network mostly cleaned up.

I have not determined uses for all of the computers yet, but one of them contains my entire DVD collection of over 500 movies, so that one will be a media server. One will be used just as a regular desktop computer, one will be an asterisk server. The other 2 I have not yet determined what to do with them.

The entertainment shelf.

This is a slow moving, ever evolving project. The AV distribution system is nearly complete. I just need to connect the Xbox to the system (or its replacement if I decide to get a new gaming system) 

I actually placed a small (8 to 10 inch) fan behind the AV shelf blowing air out the front of the cabinet connected to a switch on the side of the cabinet to prevent overheating of my Onkyo receiver.
