The rebuilding of the the HT center has taken longer than I wanted, but as of Saturday morning the system was back in place and operational again. Will be finishing up the trim and a few other details this week and then back to other projects. The roll out racks work very well, the temperature control unit is set at 85 degrees and it appears that only having one fan in each rack unit will be adequate. Will post some pictures of it and the rack wiring, at last count I had used over 500 wire ties to secure all of the cabling and needed to order about $350 of new cables which needed to be longer. The average length of a cable that runs from one rack to the other is 20'...........and the width of the cabinet is only 65".
