And if you're NOT up for lugging the modular around to gigs, then you might find THIS useful: https://www.addacsystem.com/en/products/frames-and-power/addac901m-monster-frames/addac901m-21u-monster-frame
As a fixed setup, it doesn't get hardly any better than this. Crazy-stoopid depths for super-deep modules, HUGE power capabilities (20 AMPS!) and even with shipping from Lisbon, it'll still come in cheaper than the 4-row Doepfer Monster. They also have a somewhat more sane 15U @ 197 hp cab, plus you can also get a 2U double rack "crown" which would be pretty useful for housing a pile of tiles...both Intellijel AND Pulplogic, depending on what tile frames you use.
