Pros: - Good price - Small form factor

Cons: - Noisy fan (not huge deal for me as I have it sitting in a utility room) - Nuisance to boot from USB

Overall Review: As some other reviewers mentioned, it's difficult to get the product to boot up from a USB drive. Couple tips: a) use the USB 2.0 ports and not the 3.0; b) there is a boot override menu in the Save/Exit menu of the BIOS to select / force to boot from a specific drive. I was able to use this vs. specifying a boot order to give the USB drive priority (which didn't work) to get the computer to boot from the USB stick. pfSense runs without issues (at least the first few days).
