Since ca. 2016-17 I'm running a miniITX-based home server with Btrfs 
RAID-1 (data and metadata) as main storage. A really modest system built 
from parts, Core i5-6600, 8GiB RAM. It's an n-th incarnation for that 
system, but the first with Btrfs. Somewhat inspired by [1]. It serves as 
1) an archive of personal digital stuff/cruft, 2) current backups of 
home workstation (digital photography hobby, some videography, all 
Linux), 3) DLNA/UPnP storage and service (Gerbera, formerly Mediatomb) 
for images, audio and video. So far it was completely problem free. It's 
on Back-UPS, sufficient to survive power outages, which luckily are very 
brief in this NH town. Using Btrfs RAID features implies one is aware of 
proper procedures in case of e.g. disk failure [2].

Elsewhere (i.e. $work) I started using Btrfs even earlier. Mainly for 
backups and archives. Daily/weekly/monthly snapshots before rsync for 
current (replacing rsnapshots with hard links). Btrfs snapshots are 
instantaneous. No Btrfs RAID until recently, as all storage was already 
HW RAID.
