also, watch your module depths, as the Rackbrutes really only have about 40mm in practicality.
-- Lugia

According to the Arturia website —
The max depth available on a RackBrute 6U is:

53mm on the upper part. (power bus)
75mm on the lower part. (no power bus)

-- Footage

That's so weird. The Rackbrute's own power supply is listed as 80mm Deep..
