I was wondering if anyone else was considering racking a pair (or more) of GT Bricks. I think the layout could be improved by doing this as well as the looks of the unit. Moving the XLR's to the rear with the power and keeping the trim, DI and power switch up front. The A/C could be rewired so that only 1 power cord is needed to power the units. I figure you could get up to 4 bricks in a 2U chasis (although I haven't tested it) . If anyone else is interested in this type of project maybe we can all work together, group buys on parts or whatever. Kev, if your interested or if you would like to just provide guidance for some novice DIYers it would be greatly appreciated.
