PC Engines APU2 mini-ITX bracket

Thank to this bracket, you can install PC Engines APU2 board into cheap (approx. 20 €) mini-ITX case. The bracket is in two versions, one with Raspberry Pi and second without.

Something about my installation:
- [Chieftec IX-03B-OP](http://www.chieftec.eu/en/chassis/itx/compact-series/ix-03b.html) mini-ITX case
- [APU2D4](https://www.pcengines.ch/apu2d4.htm) is running [pfSense](https://www.pfsense.org/)
- Raspberry Pi 3 is running [Pi-hole](https://pi-hole.net/) and [UniFi Controller](https://community.ui.com/releases)
