I have a similar one, but it gives up two NICs for an HDMI port - not ideal, but it was much cheaper at the time, and I have no need for a DMZ and no shortage of switches. It makes an excellent pfSense box!
I've recently bought one of these and it's been great so far. Though its a NanoBSD currently you can squeeze an SSD in there.
Twice the price of FX160 :) I have one FX160 for over a year with bunch of home software inside docker containers and works like a charm :)
Yes true, I might pick one up. The Atom I wasn't too impressed with in an old Shuttle but that has changed I think.
They make fanless metal body mini computers and come in many variations on aliexpress. I purchased a unit a few months back to run pfsense (free routing software based on freebsd). They normally use intel based motherboard/ethernet ports in 2-4 port configurations, making them good stable platforms. They usually take a few weeks to arrive because they ship from China. They don't have the polish of an apple product or sell under a popular brand name, so they are not well known.
You can get them on Amazon, too, and my impression is that buyer support is better there than on Aliexpress.
Another option for industrial and fanless in europe is Logic Supply. I bought my "home server" from them. A very simple Xeon box with internal SSD that I use as hypervisor with a homemade iSCSI NAS for storage.
