can the RAM be upgraded to 32 gigs?

Hi Taylor- I just pulled the side cover on mine and all four of the memory slots are populated. In order to upgrade to 32GB you would have to purchase 4x8GB and replace the 4x4GB that are in there. Regardless I'm thrilled with the performance and have yet to see more than 6GB of memory in use and I process very large image files for astronomy.

how many watts is the power supply?

the power supply is 850 watts on this pc

Can the Graphics card be upgraded or another card added?

I know this question was asked I checked the sight but it dose not say so I will ask agian dose anyone know how many watts is the power supply??
