At one time a premium amenity, tempered glass is now commonly found on cases, including several sub-$100 models. Cooler Master's new MasterCase H500M doesn't hit that price point, but it does go all-out with tempered glass, with the front, top, and both side panels made of glass.

Users who are concerned about airflow can eject the front panel and replace it with a mesh one, both of which are included with the H500M. Either way, you'll be able to see the RGB fans that adorn the front of the case.
