can you play online right out of the box, or do you have to sign up to something, and/or run it through your pc modem?

you need to connect it to some source of the internet..whether it be the router or some A-B switch that has it directly hooked with ur PC\'s source of internet (if you dont have a router)

and the ethernet plug is already in the console, so all you need is the cable

and sony\'s online is free

you can replace the HD drive with any portable drive, it\'s easy and they show you how in the PS3 booklet.

or some A-B switch that has it directly hooked with ur PC\'s source of internet (if you dont have a router)

Can you tell me how exactly do you achieve that?
