Anyone use their MBP and leave it running 24/7 closed - kind of as a desktop? looking to replace a mac mini, so it'd need to sit under the TV in the lounge as a plex front end and server. Then I'd either sleep it when not in use or pull it out for use as a laptop. Would this have any issues in terms of noise/temperature/life expectancy? when idling will it sit quietly in closed mode?
