I had the privilege of supporting Sun servers for a couple years out of school. They are by far the most robust pieces of hardware I've ever worked with. I remember vividly being introduced to the 1280r as it was the largest server we had in the lab. As a young and fairly inexperienced technician that thing both wowed me and scared the crap out of me. Sun's awesome old hardware prompted me to obtain a 280r, but I due to life and kids I haven't had time to do anything with it! I imagine it would do quite well as a web server or a front end to a storage "farm". But alas...time and money.
