most 60% boards have the escape key set up that way. You might want to look at a programmable board for that, but I know on the poker 2 you can flip a dip to change rctrl with `~, and on the 660c (660m as well?) they have shift+esc do ~ so you don't have to use 2 modifiers (which I personally really like). If either of those solutions doesn't do it for you you should probably look at the gh60 or thereabouts. I can't speak to the pricing scheme, but I'm sure they have a premium for installing rgb leds and there's bound to be some form of configuration stuff for it on board, plus they have to get the mx rgb switches. Seems pretty standard, though leds don't do it for me so I have no clue.
