What Hard Drive to choose for my HP Pavilion 7760

[mattblack]

Hi
I have an old HP Pavilion 7760 that I am rebuilding for my son.
It currently has as Seagate U Series 5 20GB ST320413A in it, and I want to know of a Seagate U Series 9 160GB harddrive ST3160022ACE will work in the PC.
Or is there a better hard drive that is more suited to the computer. My son will only really use the PC for homework, surfing the net and the kids online games.
Kind regards
Matt
