The Sunbeamteach Rheosmart 6 is, overall, a very good fan controller. Its black mesh design will help it blend in with any cases with a similar facade. Its ability to control six fans will be enough for all but the most fan-crazy PC enthusiasts. It can provide up to 30w of power per fan, so no matter how large or how beefy the fans you have are, the Rheosmart 6 should be able to handle them with ease.
