Due to vibration issues with my gear inside the HT I finally got it all out. Over the past week I built this on the exterior side of the HT with all materials I had at home for other projects, all the parts did come from Home Depot. Here are the pics from start to finish. I had these racks from left over from when I first built my HT. Each shelf can support 250lbs. It's screwed into the studs of the HT with 4" deck screws. I also installed a 20amp dedicated line off the main house breaker for power. The shelving is decoupled from the HT using a neoprene washer and a flat cut washer. This helps dramatically reduce vibrations. I started to install the shelf brackets and shelving. I also installed 3 1" diameter holes to the inside of the HT for all the cabling and wires. I used schedule 40 PVC. Each shelf is also decoupled from the bracket using flat cut washers. A rough layout of the interior. The finished product. Everything in it's place. I am using the leapfrog RF system to control the geare from inside the HT. An access door in the back provides all the room I need to access all the connections. Needless to say that this thing is so well isolated from the HT that vibrations and cooling is no longer an issue.
