Need just enough computer to display a web page

[Mr Downtown]

As some of you may remember, I want to put a dedicated computer in my apartment building lobby to display the next bus arrival times. We might find an old PC that someone is discarding, but if we don't, is this PC sufficient to do the job?

I don't know what kind of magic is needed in the browser to display a constantly updated web page, but presumably any browser from 2005 or later would work, right? The website in question is http://www.ctabustracker.com
