3. Build a few projects - to make sure they build.

Wine, Wine Gecko, VLC should give a good coverage.

That sounds like long running tasks so we will likely need new hardware 
so the TestBot can run them for every patch that gets submitted: if 
patches come at a rate of about one per hour, then the TestBot needs to 
process the resulting jobs at a rate of at least one per hour. That said 
we already need new hardware for PCI-passthrough for Wine (though the 
exact details are not set yet).

The rate of patches is much lower than one per hour. If tests would be ran on every git push, I'd say it's around 1/day on average, sometimes a few. I don't know how many manual submunitions there would be.
