You don't have to mount it really.
If you have the SATA connector on the motherboard just plug it in with the power also and just it lay inside the case while you access the data to backup. If your thinking is to leave it in then you would need to mount it and is there a internal 3.5 bay free other then the one the floppy drive is in?
The HP don't have any SATA connectors on the MB anywhere that I can see. It appears that I may be abl to put it behind the HP HD but untill I take it apart I wouldn't know for sure...These computers are to small for my blood..That's why I like building cause you can get a case where your hands can fit...
My bad the MB does have the SATA but the HD don't..
