Here is a current picture. Picture 1 is at home, the second at my best friend.
At home are 2 Pis for each StorjNode. 14TB and 8TB. (One Pi with 32bit because of Zabbix, the other with 64bit) My Lightning / Bitcoin full node is running on the third one. (black case)
At the second location there are also two nodes with 14TB and 8TB.
The hard drive on the side is very old, I guess 11-12 years. But still sufficient for unimportant things and for testing.
The rest of my nodes all run on virtual private servers.
