MHKB (MiniVan Hacking Keyboard) was a premium alumunum case designed to fit USB C based Minivan-compatible PCBs.
50 units were produced (25 each of E-Series and S-Type) and were sold for $265 as in-stock items on TheVanKeyboards.com. Kits included the four case pieces and assembly hardware.
MHKB was a thick, heavy, high-profile, three-layer sandwich mount case made from CNC-milled aluminum. The cases were anondized in one of two finish colors - Industrial Gray and Fabulous Teal. The board was comprised of four pieces named TOP, PLT, BOT, and SHU. The case was assembled with ten M3 x 12mm socket cap screws that were installed through the bottom of the case.
TOP - the top plate which was the cornerstone of MHKB's design. There were two options for top plate styles that included integrated blockers. The two styles were named E-Series and S-Type by the creators of the layouts. The top plate was the only piece that was different between the two variants.
PLT - the switch plate on MHKB was 5.1mm thick. Small cutouts were added inside each switch position to allow the switches to clip into place properly. The switch plate supported a single MiniVan layout - specifically the Southpaw + Arrows layout. This layout was chosen as it allowed for compatibility with both top plate options. The plate also included three small holes between the first 4 keys in the top row to allow the indicator LEDs found on the MiniVan HS PCB to shine through.
BOT - the case bottom included the same PCB support ridges found on the MiniVan aluminum case and other MiniVan tray-mount cases. 3/4 inch foot wells supported the included cork pads and also doubled as a mounting point for SHU.
SHU - the optional angled "foot" which held the board at a six degree typing angle. It was attached with four countersunk screws installed through holes in the bottom case. These holes were covered by the case feet when not in use.
Several prototype cases were produced that included a unique blocker combination that was not included in the final production run. The top plate featured a 1u blocker in the bottom left (similar to the E-Series style) and a 1.5u blocker between the spacebars and arrow cluster.
The E-Series MHKB was a Happy Hacking Keyboard-inspired layout with balanced 1u bottom corner blockers on the top plate.
The S-Type MHKB included a single unique asymmetric 1u blocker placed immediately to the left of the spacebars.
