a hdd is cheap most people will have a extra 2.5 laying around. i do but it is only 20GB so thats worthless to install
the battery i dont know if it holds a charge i have never used it. i will take some pictures later tonight i just got home from work
looking on ebay this computer is about $400 with the same type of stuff
a battery for this pc is less then $30
here is one on ebay right now that is missing the ram backcover and he is looking for $500

If anything i will just get a hard drive + the screws and a new battery if it is needed and sell it like that. I think it might be a better outcome.
* im going to test the system right now do a charge of the battery + see if it hold a charge. if it does i will buy a brand new hard drive and sell it
