CannonKeys's F12 TKL follow-up ships with top mount, single-sided gasket, and o-ring hardware in the same box, plus a carbon-fiber bottom plate and a POM underside element it calls Volcano. The mount menu is the story.
Bolting a half-pound of brass into the bottom of a case is one of the more expensive mods in the hobby for how little it visibly does. It changes how a board sounds and sits on a desk — just not in the ways the marketing copy implies.

The case is the largest resonant body in a keyboard. Aluminium, polycarbonate, and ABS each change the sound, feel, and weight profile in fundamentally different ways — here is what each material actually does.
Mode's second round of its 75% Sonnet board ran at CannonKeys from 2026-06-01 through 2026-07-15 after a vendor-side timeline shift. See the in-article update for the dates and accent-weight color options; the closed entry is archived at /group-buys/past.

An Alice-layout board with a leaf-spring F1 mount, a 9-degree typing angle, and four colorways of friction-fit silicone cat ears ran at CannonKeys through 2026-05-17. The mount type is the editorial story; the cat ears are the conversation.
