Thank you all for the suggestions. I will grab a test suite or two and do some burn in testing over the upcoming weekends. These machines are new, built from scratch. I've been building systems for over fifteen years and haven't had anywhere near this amount of trouble which is really aggravating! I realize garbage in equals garbage out and some of the chosen components are pretty low-end, but I did spend close to six months researching the components, and couldn't find substantial evidence to dissuade me from any of the choices. The only parts not new are the 250G seagates where are basically left-over parts from an old server that was upgraded. They're all known-good as that server gave me no trouble through its service life.
