I’m revamping my studio at the moment, and figured out the 2400 was rackable with a little bit of work. I found some generic rack ears, and drilled some extra holes to match up with the SP.
MPC Live right above it, racked with a VESA rack bracket and some metal angles drilled for screws and covered in black tape. The SP was just a little too wide to fit in the VESA bracket, but worked fine with the ears I found.
