I have my old computer I bought in 2007, it is an Core2 Duo 6300. It has a 320GB hard drive, I am running Window 7 Ultimate 32bit, 2GB Ram Bios Ver. 3.14. Can I put a 120GB SSD in it? I am also thinking of upgrading the Ram memory to 4 or 8GB if I switch to Windows 7 64bit. I'm not sure about the mother board, it is a HP Media Center, can you help?
