For the love of God, do not get a Seagate 7200.11 refurbished. They are garbage new, I can only imagine refurbs.

7200.12 is much much better, 7200.11 is known for the awful click of death. I beg of you, please don't get the 7200.11 refurb.

You know how some systems operate clunky under XP? My friends laptop is like this, every thing you do is just slow, opening a file, opening a folder, etc - everything is slow as ***. Even opening firefox takes like 15 seconds.

This is what I don't want.
 
As long as you're installing the OS, just install the basic stuff. All I install is Firefox, AVF Free, Adobe Reader. MS Office in your case.

Most peoples computers are slow because they click, download and install every single link they see.
 
I think there will be an improvement if he opens say Word, Outlook and like 5 web browsers at once.

I personally would go with 4 GB if you can spare it. It would certainly future proof the build a bit more. Also, it's one less resource you can pretty much never worry about.
