The RF—8X by keyhub is a custom 80% electro-capacitive keyboard housing designed for enthusiasts of Topre and rubber dome keyboards. It combines the classic design elements of Topre's Realforce R1 with the minimalist aesthetic of the now-defunct Noxary's XRF. The project aims to support friends affected by a prior scam while showcasing a design that the creator admires.

Key specifications include a typing angle of 7.45°, a front height of 17mm, and a top mount style. It features a unified daughterboard with a USB-C port and is compatible with Realforce R1 86/87/89u internals, as well as Realforce R2 internals with an additional custom plate. The kit includes the top and bottom housing, a USB-C daughterboard PCB, custom JST cables, screws, and a protective carrying case.

The RF—8X is available in various finishing options, including silver anodized aluminum and frosted polycarbonate, with a housing kit priced at $350 and a plate option at $40. Potential buyers can expect delivery around Q2 2026.
