What kind of hard drive should I get for my Acer GX-781?

Hey everyone! I recently got an Acer GX-781 from a family member, but it didn't come with a hard drive. I'm not really sure what type of hard drive I should be looking for. Can I use any hard drive, or does it need to meet specific specs? I understand this PC is a bit older, so I'm not expecting to run any heavy games like Genshin Impact, but it would be great if I could play something like The Sims. Sorry for the newbie question, and I appreciate any tips you can give me! (Also, English isn't my first language, so I apologize if I'm using any terms incorrectly.)
