Great turnaround and build quality was fantastic, good communication too. The hardware all works well. I order it without an OS as I am custom building an AI monitoring and filtering system for a school. I installed Ubuntu Server 24.04.2 LTS and it runs like a dream a few driver issues with onboard LAN Realtek card and not using built in Wi-FI but had additional cards installed, 10GB Ethernet to handle traffic as this machine will be the DNS for the school filtering all traffic. Anyway got the stock driver from Realtek installed and works fine. Running Pihole, Squid and e2guardian for DNS filtering and keyword filtering, prometheus, Grafana and Kibana for reporting dashboards. Will be installing YOLOv8 AI for image and video filtering (That will test the system resources). Overall I highly recommend PC Specialist.
