Custom core booted Optiplex 3050 micro with EDK 2 payload, capable of booting Modern UEFI operating systems. Great little server box, I have run immich, nextcloud, the arr stack with jellyfin and navidrome on it using both dietpi and zima os. I recommend zima os if your interested in doing a similar setup. I have both the i5-6500 it came with and also a 7th gen i5-7500. I also have a wifi card available I have been using but I dont have the official dell antenna for this pc, I just routed som laptop antennas I had from a broken monitor I routed to the outside of the device which works completely fine but I will admit its not the prettiest looking setup, so Im not charging anything for the antennae obviously. if you want to get the official dell antennae you can always order it separately
