The RackBrute 3U and 6U cases are actually 89 HP wide, and if you replace the PS panel, you've got an extra 2 hp.

I'll be darned if you're not right! :)
Today I received my Quadrax QX Expander after searching for one for the last 4-5 months. It was the last component I needed in order to fill out the top row of my Rackbrute 6U. With the rack on Modular Grid, what I had in place for the advertised 88HP fit perfectly, but after moving my modules around to match how I had it laid out on MG, there is 1HP gap at the end.
I wonder why they didn't just build ventilation into the side of the panel? even a smaller circular vent would have been very efficient I think. I don't know how effective a 1HP gap will be but I guess its better than nothing.
