Well I can say with absolute conviction that Sun is definitely off the list of choices for hardware. I tried they're 'Contact Me' to get a quote and all I got from them was a couple promises of they'll have someone contact me. When someone finally did (Mike W.) at Tactix.com, all I got was an email saying he was too busy and he'll try and work me into his schedule. I sure expected more from a company like Sun. IBM and Dell you can customize and purchase a system online instantly. I have to check out Atipa http://www.atipa.com and Penguin Computing (www.penguincomputing.com). Unfortunately, I think my best option is building my own system again.
