Yeah, good point. All my servers are Phenom+Asus+ECC. Honestly it is extremely rare (once I can think of) that it reported a corrected memory error but it's yet another thing that could go wrong if you don't have it. Regarding reliability, I am not convinced that "server grade" parts are all they are cracked up to be. By far the least reliable hard drives I have ever used were a batch of enterprise RE2s where 6 of 6 failed in less than 5 years, and all the warranty replacements also failed. That is very anecdotal but does prove that buying "server" parts is no substitute for other disaster recovery measures. I currently run only decent brand desktop-grade parts (plus ECC RAM) and use the left over money to buy standby hardware so I can quickly swap out anything that fails. In the past 6 years or so that I have run LTSP servers I have yet to have a bad CPU, motherboard, or ECC RAM stick. YMMV.
