Mac Mini as DAW

Hey there all

been getting into alot of audio production and now feel i need to upgrade from the old laptop to a decent DAW setup. My question is, what are the mac mini's like for audio production, the reason being is i already have a 32in lcd screen in the room i wish to set my studio up in so thought may as well just use that.

Will be running either logic or ableton, midi keyboard, extrenal sound card and good quality studio speakers.

So should i be fine with the mini or just go the imac as i dont have the $$$ for the mac pro at the moment.....
