Firewall or Server

I have an old 1U enterprise Sophos XG330 firewall. It has an i5-6500 and 12GB of RAM. It has 10Gbps SFP+ and the rest are gigabit. I'm selling because it takes up too much space. You can install any OS on it and you don't need to use it as a firewall. It will not come with an SSD/HDD.
