so im walking to the park to day with my daughter and in somones trash is three computers. monitors and al. one being a high def sony 19 inch

1. pentium 4 sony viao
2. pentium 4 compaq
3. gateway gm5260
none of these have hard drives the owner said he smashed with a hammer which i confermed when i opened them. i want to get the gateway going but what do i need to know about the hard drive in this thing to get it working. the hard drive was still in the comp and i pulled the sticker off of it. can i put the hard drive in my current computer without to many issues? i know their will be some driver problems but i can figure that out. also the sata cable needs to be replaced but everything else is in good shape. any info would be greatly appreciated. thanks
jonny
