Akasa Newton NUC Case @ techPowerUp
 

Intel managed to turn some heads with the NUC, but with its active cooling solution, it leaves things to be desired in terms of noise. A few manufacturers have stepped up to offer passive cooling platforms, one of which is the Akasa Newton. Competitively priced and with a good feature set, it has all the right ingredients to make for an excellent silent solution.
