Another quick update, I’ve rewired 80mm fan and power button and bought a 24pin extender for PSU, much less work and if I ever want I can use the PSU again and without extender… Now it is a working PC, except it doesn’t have a disk… 
So I will test it for now with live USB when I get some time…
The next thing would be to add some improvised dust filters and to check if there is need for another fan on APU…
I will probably find some SSD to use or I will use SSD from my x58 workstation after I upgrade that one to NVMe…
Here are some pictures of the front:
and the side:
and compared with 0.5L beer can for size:
I still don’t have a lot of time to work on this, but when I get some free time I will buy the switch, AP’s and then I will setup the network… After that I will start to look for a hardware for server build and I could probably make that as separate topic with more details, hope I will have more free time to do that…
