The maximum RAM complement for that system is 8GB using 4 x 2GB DIMMS. You would need to be running a 64 bit Operating System to utilize 8GB of system memory. With a 32 bit OS, 4GB would be the maximum usable, although some would be inaccessible. The memory complement wouldn't require any alteration to cooling or PSU.

The best way I've found is to use Crucial.com and either scan the system or use the manual method.  If you do the scan Crucial will tell you how much RAM you have installed, how it is installed (how much in each slot).


Adding RAM should not require an additional parts.  You just need to make sure, as Platypus point out, that your operating system will be able to use the amount of RAM you have installed.  You can install more that the operating system will use, but you would need a 64 bit operating system to actually be able to use more than 4GB.
