Some specs from reviews or retailers · sources

Sold on Glorious's UK store in GBP (£249.99 for Black and Silver, ANSI only, wired; both in stock when checked, though the listing is tagged end-of-life). Glorious's own compatibility page guarantees only Glorious HE switches (Fox, Lynx, Panda and Raptor HE are listed as supported switches here); the PCB also takes standard 5-pin MX mechanical switches, which the builder will flag because the board is recorded as Hall-effect. Third-party magnetic switches such as Gateron Magnetic Jade are not supported. Plate-mount stabilisers come fitted, based on Glorious's marketing and its stabiliser-swap note; the page's 'what's included' list does not name them, so treat as medium confidence. The aluminium plate is standard (polycarbonate and brass plates are sold separately). Four sample HE switches, a braided cable, pullers, screwdriver, spare screws and O-rings are in the box. There is no QMK or VIA support, only Glorious CORE software. Weight (2,091 g) is from the Shopify product data. A UK ISO version of the HE barebone was not on the UK store.
