I'm sure it varies by system and the specific hardware, but I don't think it was too bad when I did it and I'm hardly a Linux expert (I've been using Arch for a few months). There will probably be a couple hurdles as you'd expect from a fairly custom Linux install, but the extensive wiki and large community make it relatively quick and painless to figure out what's going on and how to fix it.

That said, if you're looking for something as quick and easy as possible you might want to look around a bit more to see if there are any prepackaged systems that do exactly what you want with less setup. No sense making this more complicated than it needs to be if something else comes up that closely fits your needs and could potentially save a couple hours of troubleshooting.
