I built this out as a backup for a client, though its no longer required . It is currently has PF Sense installed and intended as a  Firewall and Router. It is currently Running PF sense 2.6 . This is a  handmade Bespoke Ultra Small Form Factor Mini PC, with PF sense installed ,  made from mostly new parts ,  fitted with a full size four Port Intel Gigabit Ethernet Card  For Firewall and Routing .  

This could however be adapted for many other uses , including Server , NAS , Home theatre PC or Desktop . For example  A Full size raid card could be installed , alongside housing four SSD's 

The parts for this build were incredibly challenging to source and put together, this took hours of research and weeks of waiting for shipping .  .
