I really, really appreciate the advice, and if Trogtronics weren't backordered I'd get one today. However I found someone local to me selling a 9U 126HP Erica Synths case with 1.25Ma per row on the + and - 12. Seems like it'll do the trick, and it'll even have more room for extra modules! I won't need to sell a few that I don't have room for!
