I have set up and maintain 2 Mac Mini Server setups in 2 architectural offices. Has been running flawlessly for the last 5 years. One of them I restarted the other day after 364 days uptime. 

Both are still on 10.10.5 and use a Promise Pegasus2 Thunderbolt hard drive, which is lightning fast, reliable and can handle lots of concurrent users. 2 swappable single external drives for a time machine backup of it, which I swap out every couple of months. Plus we use Backblaze to back everything up to the cloud. 

I would add, that I would recommend adding an UPS to it. We use the APC 900 for it and it can get a good 20 minutes of battery power for the mac mini, hard drives and network switch. Plus it adds protection to everything as it will smooth out any spikes in the power. Nothing like your server not being effected by a tripped fuse, lightning or short power cut.

I think Face ID actually makes a lot more sense on Macs then on the phone, because the touch ID sensor would always have to be on a peripheral - except on laptops of course - but even there I would rather have it scan my face. I rarely need to unlock my computer or authorize something without looking at my screen. Makes much more sense there.
