The 2012 iMacs are very very cheap, and they have what is needed to keep a radio station online, a vlog editor and a lot of other nifty things that only Apple has. The 2012 line of computers from apple with max ram will give you what you need. Right now I am on a podcast with windows users, and so far the hosts has crashed 2 times during 4 hours. Would never happen on a mac from 2012.
