There is a PCI-E x16 slot in mine (verify that there is in yours too to make sure). As for the PSU...upgrading might not be a bad idea, I don't know the exact amps on the 12V rail but I could imagine it isn't very high. I'm too tired now to check but I'll pop open my parents case tomarrow and let you know.
