Coriander is a case for Minivan-compatible PCBs with USB-C ports. It is made from an acrylic-based solid surface material that is typically used for artificial stone countertops (brand name "Corian").
Coriander is a high-profile, three-piece, two-layer top mount case. The top and bottom case pieces are machined from an acrylic-based solid surface material. The switch plate is secured to the top case using four M2 screws installed through tabs on the top and bottom edges of the plate. The middle "layer" is a metal accent ring that sits in a lip around the outer edge of the bottom piece. The accent ring is not required to assemble the case. A detachable foot elevates the case to a 4 degree typing angle and is made from the same material as the top and bottom pieces. The case pieces are assembled using M3 screws installed through the bottom of the board. The board will include a sheet of cork and a stencil to cut out the two wide cork strips to be installed on the bottom.
The board is expected to use an artificial granite or marble design for the case material. A poll was posted in 40% Keybopards Discord for users to vote on their preferred material color and pattern for the production cases. The final winning color has not been revealed. The #1 Trash Man made the decision to run the case in the same color as the prototype case.
A single prototype was produced from white Corian.
The first and only group buy for Coriander ran in August 2021 on Trashman.club. Cases were sold for $330 and buyers were given the choice between the "universal" top or an S-Class top piece that includes the same 1u blocker as the S-Type MHKB. The Coriander kit included the case top, bottom, and angled "ramp" made from Corian, a copper accent ring, and "universal" POM plate that supports all Ketch layouts.
