I'm going to have to dig a little deeper. I know it only has 1 stick of ram inside now.. The processor is an Intel Xeon E5.

I wasn't able to check the installed ram.. It has 4 hard drivers, all SATA but unsure of sizes.. Can't seem to find the info I need in the BIOS --

If there is a way I can check this stuff WITH the computer locked, let me know and I can check it all for you.
