Great little Linux box. Assisted RAID-10 setup worked flawlessly; stability has been incredible. Mine is running CrashPlan and other Java services, as well as BIND9, HTTPD, and syslogd. Used two 3rd party (G-Skill) RAM modules purchased from Newegg to increase to 4GB
No redundant power supply and RP model costs ~$600 more; Web management interface is quick but only moderately intuitive until you get used to it
