I've got 2 desktops and I want to get rid of the older one but I would like to take the 2 hard drives (80GB and 160GB) and add them to the newer desktop which currently has a single hard drive (320GB). How can I determine if this machine can take on 2 more hard drives and is what I'm doing common practise or does one just go and buy a new machine with a larger drive. Sorry, I don't have access to the specs right now but are there certain things I need to check or look out for or is it basically just mounting the drives and connecting them to each other and away I go?
