I wanted to see how small I could spend on a dedicated ALPR machine.
I found a cheap ASRock FM1 motherboard, PSU, and old SSD in my closet. I got an A8-3870K CPU for $30 on ebay. I found a 2U server chassis to hold it https://amzn.to/2LIGFke. 4GB of memory was barely enough for the OS and OpenALPR so I upped it to 8GB for another $40 https://amzn.to/2BTZ0Gu. I used a PCIe dual ethernet card to talk to the main vlan and the camera vlan, isolating the cameras from the outside world https://amzn.to/2Vkwbfr.
The machine uses ~80 watts of power during the day and ~40 during the night (less motion to detect in the environment so less processing).
Overclocked the CPU to 3.2GHz and started feeding it 2 cameras.
Even on several generation old hardware 2 cameras are easily supported.
