AMD X2: Dell E521 or others?

[Claus Assmann]

Is anyone running OpenBSD on a Dell E521 machine (it seems to use
an "NForce 430" chipset) with AMD X2?  I'm looking for new computer
with a dual core CPU for some performance testing (no "multimedia"
stuff needed, some "cheap" machine will be sufficient). I also would
like to run SunOS 5.10 on it, please let me know whether you have
a machine with an AMD X2 and both of these OS run on it. TIA!
