Hey guys! I'm pleased to say that I've yesterday bought a wonderful retina 5k iMac. Everything is good, love it! Works great with my iPhone and macbook pro retina too. Only thing I'm wondering if it's normal to have a ever so slightly small amount of air coming out of the bottom speaker holes of the iMac, It's mainly when playing music (speaker quality is TOP NOTCH!! Wonderful!). It's not much, you can just feel it a little. Thanks!
