Okay simple question 2012 mac mini A BTO with an external power supply. This allows a quad core and a discrete graphics card . would you buy it. yes or no. Please I have posted about this and have had some very strong opinions for and against. Right now the design will not allow for both the quad core and a discrete graphics card. Two reasons you need about 100 watts PSU the current psu is 85 watts. The psu bleeds heat about 10 percent. so an 85 watt psu maxed will bleed 8.5 watts of heat. The old psu was 110 watts and it kept the heat out of the mini. going back to it wrapping it in the same aluminum. allow it to plug into your wall socket directly and putting a pass through socket so you do not lose both plugs is all easy to do. making a connector that only allows it to go into the bro mini is also possible. As of today no quad cpu discrete graphics card combo uses the required power for the current psu. So I bring this up as a simple poll. Would you want it. remember the current machine does plug into the wall. So a power cord is needed one way or the other.
