Dell DM061 Upgrades?

Hi, 

I'm a Dell community newbie. I have an old Dell DM061 (Intel Core 2 4400 @ 2.00 GHz) with 2 GB of RAM. I am wondering:

• what is the maximum RAM that this machine will accept? (2 x ?)
• many drives are possible to install? What are the physical limits? I want to repurpose it as a home server. 

I understand that some of this information is available on spec sheets. But I have seen on these forums that what is actually possible sometimes surprises. 

Seeking wisdom from the Dell community. 

Thanks,
