Gowin GW-R86S computers are well suited to be software routers. I have mine in a «poor man's network rack», a wall with a DIN rail*.
This part suits thicker r86s models with 10GE, namely [GW-R86S-G](https://www.gowinfanless.com/products/network-device/r86s-firewall-router/gw-r86s-g-series) and [GW-R86S-U](https://www.gowinfanless.com/products/network-device/r86s-firewall-router/gw-r86s-u-series) Series
It works well when printed in PETG. You'll also need 2×M4 screws and preferably 2×M4 washers
When mounting the machine, look out to keep the air inlet and the power button free!
*DIN rail means: top hat rail IEC/EN 60715 – 35 × 7.5.
The author remixed this model.
The PSU DIN rail mount (55mm) is used as a part of my design with no changes. It does its job well.
