There’s an old YMDK aluminum enclosure for Filco (and other Costar generic) TKLs that’s pretty darn tall.
It’s called the F87 and should fit any wired Filco TKL and some random stuff like old Cooler Masters, a Turtle Beach keeb called the Impact 500, and a few others. It turns the donor board into a top-mount, and has a tall base height. I seem to remember the stock feet making for a steep angle, but it’s possible to put taller feet in their place if desired.
I don’t necessarily recommend this as a premium option, but maybe as a quirky / fun project.
