as all ready posted
no need to get a new battery, al though thay are cheep, all the battery will do i hold the settings like date time tye of HD etc etc so with out the battery you may just have to reset every thing each time you re boot. if you not going to keep it doint bother.
getting the password, crack the box and google the mother bord, but then why bother. and as posted you could have fun getting the picks on to sum sort of movable media.
just flick out the HD and change the jumpers to slave and plug it into your mates machine, or even just drop it off at any back yard computor shop
