Solaris 10 on Sun W2100z workstation?

I am looking to buy W2100z workstation. I want to run solaris 10 on it.
I realize it's a few years old, from 2004.

Is it a good machine to get or should I look for a newer workstation?

I believe that workstation has gone EOL (end-of-life) and not oderable anymore. Its best if you could get a new workstation like Ultra 20
