Yes, but will a system from 2003 be as useful, even though the OS is still supported? Remember, you're talking about systems from the Pentium III era, 750MHz or less, with 512MB or less of RAM.
That's more like the mid-range system I had in 2000. Not a huge difference, but it would be 13 years old at this point. My computer from 2004 that I still use regularly is a P4 2.4 GHz, with 4 gigs of ram. It runs everything I need quite well, with the exception of some of the fanciest new games. Even those would run with reduced graphics if I had to play them on that tower.
