Sun Blade 1500 "Red" running Solaris 10U9 - my old development "server"
Next to this is an Excito Bubba B1 Ultra Mini Server with an ARM 200 CPU, 128MB and a 500GB 7200 IDE Disk running Debian 5.0.6 used as a NAS server offering NFS and SSH services.

The Blade 1500 is currently a "retired but spare on a moments notice" machine.
