Sorry, I was referring to the form factor. you can hop on aliexpress and search for topton. There's a wide variety to choose from. Some are barebones with no ram/ssd. Some have 6x 2.5G others have spf+ for 10G or a combination. they're small, quiet, energy effecient, and made for being a router/firewall. There are other similar brands, but this will get you shopping in the right direction for what I was referring to.
