You have a couple of options to find out:
If Linux is running on the box already, goto this site:

Download, unzip/uncompress the data file and try installing it. It takes a bit of time to use how it works (i.e. documentation sucks).
---
If you are running Windows, goto this site:
http://www.belarc.com/free_download.html
Run the Belarc Advisor and it will automatically detect everything on the box -- hardware, software, license keys, etc.
---
For a drop-in, bootable CD ISO image, goto this site:
http://www.sun.com/bigadmin/hcl/hcts..._check_sx.html
The Solaris Express Installation Check Tool will determine if your system can run Solaris Express, thus will output everything hardware related to the system (i.e. drives, video, memory, etc).

Also try out Memtest86. Although it won't give a hardware inventory, it can determine the ram type installed.

Hopes this helps.
