According to the order form, from when I purchased the system, it is the 
AMD Opteron Model 1218 (Dual Core).

Thank you for this part.  That is/was my ultimate plan was to replace 
the motherboard/CPU/memory.  Per Sun, this MB has a max ram of 8 Gb, and 
I wanted to go to 16 Gb, and also move to an intel processor.  I really 
just liked the case and didn't want to part with it.

I am happy with the (2) drive bays, I have additional storage capacity 
for this system via an old Sun D1000 JBOD.  The D1000 works great for 
experimenting with different ZFS raid type layouts.

My system shipped with a DVD-RW drive from Sun.  It works great, and I 
have burned many a OpenSolaris Nevada disk with it.

Thank you for your information, I appreciate it.
