I just found this interesting thread and wanted to add.
Since 1.5 years I'm running FX160 as a Centos 7 home server and am still very pleased with it.
I bought it for a small price and added a 500GB sata disk to it and 2x2GB RAM (only 3gb is usable).
The following services are running on my FX160 without any problems:
- apache webserver
- haproxy load-balancer
- mysql server
- observium (snmp monitoring)
- smtp server
- mail server
- samba + nfs file server
- FTP and SSH server
- sabnzbd (newsgroup binary download client)
- varnish server (caching)
- DNS server
Besides the FX160 I'm also running a Wyse R90L (thin client) as a Centos server, but it is less powerful due to
its single core and 2GB RAM.
I really hope a new (hacked) bios update will come available so I can benefit from the 4GB ram.
