Mac mini i7 or iMac i7 with cubase?

Anyone have experience using a mac mini i7 or iMac i7 with cubase? Wondering if heat is a problem, with excessive fan noise. Typically I’d probably use 50% cpu power, would the fan be kicking in loud at that point? I normally wouldn’t consider a mac mini for music production but everyone seems to be raving about the i7 processors.
