My iMac G4 800 with it's GeForce 2 MX runs Warcraft III passably well. However, keep in mind that WIII has some pretty inflated system requirements due to
everything being 3d rendered.
I hear a lot of angst against the iMac, though. The way I figure it, my computer has plenty enough get-up-and-go to last me until well after it's been totally outdated, at which point I will be able to afford replacing it outright. Yeah, I don't get to upgrade one piece at a time, but face it - no matter what you do there will come a day when your tower has been outdated to the point that you pretty much must replace it to stay current. So, from my perspective, I'm just saving money, so
Seriously, I personally think the tower vs. all-in-one debate comes down to a lot of personal opinion rather than cut and dry facts. In any case, if you can find room for a tower, you may even want to check out 2khappyware.com for a cheap alternative to that PowerMac G4 that's virtually just as upgradeable (not quite as current with technology, but not all that bad considering the price).
In any case, I own one of the first "new iMac" models (top of the line at the time, 800Mhz plus Superdrive), and I love it. I vote iMac!!!
Oh, and to answer "how could she do this to [you]"? She's your Mom. Mom's always know how to bribe, I mean *cough* motivate, their children! 8)
