$90.00 Sale Save
Acrylic Case Color Glossy Opaque Red

FRL84 is a no-compromise, hotswap, via-compatible 65+Numpad layout. Primarily, the goal here was to create an approachable keyboard with maximum functionality for us number-crunchers.

General Case Details:

  • All cases feature a Frosted Clear bottom layer to showcase the PCB underglow. If you would like to skip this please let us know and we can cut it in the color you select. 
  • Features adhesive gaskets on the bottom of the switch plate and screws to keep everything nice and secure, as well as helping damping. 
  • Features a 6° typing angle with a left side daughterboard location. The USB location can also be swapped to the right side, but the acrylic will have a glossy finish for the feet and bottom. 
  • All our plate materials are available. Plate files are available by request. 
  • 3/16" (4.75mm) Milled plates are also available.
  • The build shown in the product pics is GMK Sandstorm paired with a Mint case.

    Build Guides

    General PCB Info:
    * Standard 1.6mm thick PCB.
    * Black Soldermask with White Silkscreen
    * Hot Swap, Assembled PCB (No soldering needed)
    * Full Via Support, and is flashed with a Via compatible firmware from us.
    * PCB mainboard and C3 Unified Daughterboard
    USB type-c and ESD protection

    What is required but NOT included for a finished build
    * USB Type-C cable
    * MX style switches and keycaps
    * Screw in or snap in PCB Mount Stabilizers (plate mount not supported)

    Note: Case Assembly adds additional time for production. Timelines are here.

    If case assembly is added, we will peel all the acrylic, install the adhesive strips and gaskets, and screw the case together. All that has to be done on your end is soldering (unless the PCB is hot swap) up the switch plate to the PCB and unscrewing the case bottom to drop it all into the case. 

    This is a general overview of all of our cases:

    This sale only includes the case, case hardware, and universal 36mm x 6mm x 1.5mm silicone feet. Addtional options are available as add-ons but are only included if they are selected. All other components need to be sourced from other vendors. 

    All cases are made to order. The latest timelines are updated here.
