1) It will run fully functional, yes.
2) The electric cable will not fit but it is just a standard one, you could buy another one from an electrical store.
3) You'll probably only be able to connect to the US playstation network
4) Yes, you can use your Momo with the PS3
5) Nope, you can't upgrade RAM using memory cards
6) I haven't tried it under Linux so I haven't a clue. I would've thought it would perform somewhere around a mid-range PC until they make a build that uses all 7 cores available
