Thank you DDNGUY, jayteez, Art, and Scoot2300! Your words are very kind.
They are not Middle Atlantic racks. I don't know the manufacturer, but they are industrial grade racks that are used for servers found in large corporations.
I have included some additional pictures of the racks, side by side. The front clear doors and the rear solid doors both open and close. The sides also can be taken off while keeping the structural integrity of the racks.
Here are the two racks with the doors closed:
Here are the front double doors open:
Here are the quad fans per rack:
Here are all eight cooling fans:
Here is one of the five Sony VAIO 200 DVD firewire changer (this is a stock photo, not one that I took):
The racks will be placed in my A/V room. It is between the game room (double doors) and the theatre (single door). I installed another circuit breaker box to ensure that no outlet is overloaded. I also have about 40,000 feet of cables running throughout the house that terminate to these racks for use of the Media Center to the Extenders, the amps for the whole house audio, internet and phone.
I will try to have some more photos of the theater. Unfortunately, it has not made much progress because of the holidays and other reasons. However, I am determined to have this completed quickly so I can try to get on that Top 10 list where calv1n mentioned my theater in the $20,000+ forum, and possibly even a feature in Electronic House ;-)
Thanks again for your interest.
