MiSTer FPGA Keyboard Computer Case

Note: This requires a larger printer as the largest pieces are 306mm wide. I printed mine on a Elegoo Neptune 3 Plus.

Features:

3 rear mounted USB ports

Rocker Power Switch

Internal SATA HD/SSD

HDMI port

Ethernet

4 internal USB ports (for keyboard, BT/Wifi dongles and etc)

Serial User port

5v power inlet port

And the 3 IO board buttons on top

Plenty of ventilation

I decided with this version to not include a spot on the back of the case for analog/digital audio or VGA. Also, there is no externally accessible SD card on this model. I assume most folks will transfer data over via FTP. I have included a CAD STEP file so feel free to adapt it to your needs.

Included in the download files:

Keyboard Case Top.stl - This is the top portion of the keyboard case.

keyboard case bottom.stl - This is the bottom portion of the case.

Left Side Piece.stl - This is the left side piece that attaches to the bottom case piece and helps hold the keyboard in place.

Right Side Piece.stl - This is the matching right side piece.

SATA Cover - This is the cover piece that holds the Vantec USB to SATA adapter in place

Button.stl - This is the buttons that activate the IO board buttons. Print 3 of these.

Keyboard Brace.stl - This is a keyboard brace that attaches to the top of the MiSTer stack. It helps support the keyboard in the middle top to keep it from flexing.

MiSTer Keyboard case.step - This is a master design file in STEP format. For you CAD enthusiasts this will make it easier for you to make any mods or remixes you might have in mind.

Parts you need to complete the build:

Besides your basic MiSTer pcb stack (USB board, DE10-nano and either Digital or Analog IO board), there are some extra stuff you need to put this all together.

Screws

10 x m3 x 12mm Socket head cap screws - These go into the side pieces to attach them to the main body of the case.

4 x M3 x 10mm machines screws - These mounts the MiSTer PCB stand to the case bottom

6 x M3 x 6mm flat head machine screws - 4 of these are to mount the rear panel mounted HDMI and Ethernet extension cable. You can use pan head too, flat head just looks nicer and mounts flash to the rear panel. Use two of these for the SATA HD.

4 x M3x14 Female Hex Brass PCB Motherboard Spacer Standoff - Combined with the 4 brass spacers that are included with a DE-10 nano, these connect the IO board and USB to the DE10-nano.

6 x M3 x 8mm - 4 of these are used to screw down the top of the IO board to the MiSTer to keep everything secure. 2 are for the SATA cover.

Other hardware (links to where to buy)

Vantec USB to SATA adapter (model CB-STU3-2PB) - Take this out of the plastic case it comes in as that won't be used. If you already have a MASE unit from me, then you can use that adapter from it as that's the same model

Left Angle HDMI extension - This connects from the HDMI port on the DE10-Nano to the back panel

Left Angle Ethernet extension - This connects from the ethernet port on the DE10-Nano to the back panel

90 Degree DC power plug - You will use 2 of these to connect the power on your DE10-nano and USB hub to the power switch.

Power Switch - Mini Rocker power switch. Need just 1 of these.

DC Power socket - Just need 1 of these

Ajazz AK33 keyboard - This is the keyboard I used for this design. There are several for sale on Amazon and can be sourced from other places as well.

Short USB C to A cable - Shorter cable to go from the keyboard to the USB hub. Helps clean up clutter inside the case.
