Wi-Fi compatible?

[biscui killa]

I was wondering can I get Wi-Fi with my old (crap) Dell Dimension 4600. Here are the specs :http://support.euro.dell.com/support/edocs/systems/dim4600/en/4600i/sm/specs.htm
Any help would be greatly appreciated especially if you could dumb it down for me as I dont know much about computer tech.

Any laptop or PC of any age since USB was incorporated can accept a wireless dongle which shouldn't cost you more than ten dollars or pounds on e-Bay.
