In the words of the owners: 
"This Cisco router rack provides easy access to eight Intel based servers, four Cisco routers, a Cisco switch and one Sparc II server.  It is currently configured as a multiple forest – multiple domain and Exchange test bed. The user can easily switch between systems through the use of keyboard, video, mouse (KVM) switch. The optional wheels were well worth the cost and make reconfiguration easy as the rack rolls out and back in with little effort.  The side panels added a finishing touch covering the side view of the equipment.  Also, the top cover panel provides ready access to the Radio Shack TRS-80 in case of extreme emergency.
    Needless to say I am really happy with this rack. It makes learning so much easier when you have a nice setup. This rack is really an exceptional addition to my test bed, and considering the price of this whole set-up, it's been very respectful of my wallet as well.  I am currently using it to study for my Microsoft Certified Systems Engineer (MCSE) exams and to stay current on Cisco networking."
