Macintosh - Mac Mini aficionados please help

I'm thinking about purchasing a mac mini for my wife's system. One of her favorite websites is gamerival.com. Can somebody please tell me if this site is compatible with the mac. If it's not, then I'm going to have to look elsewhere for a small and quit system. I've been wanting to try a mac for some time and this gives me a reason to jump over the windows XP fence and see what's on the other side.

Thanks,
