We include Cooler Master in this test because they offer an optional glass panel for the MasterCase 5 and MasterCase Pro 3 cases. These cases are characterized by their high level of modularity, while the cooling and noise levels are above average as well. Unfortunately the same can be said of the price; especially the MasterCase Maker 5 is far from cheap, and it does not even come with a glass panel by default. You have to purchase it separately from the Cooler Master online store or from select partners, for 43 pounds / 49 euros. An alternative is the, not tested by us, Maker 5t; it costs slightly more (on average about 207 pounds / 235 euros), but it does come with two glass panels and the necessary extra functionality when compared with the regular Maker.
While the MasterCase Maker 5 cools very well especially at 12V and is one of the quietest cases at 7V, the total price including glass panel is too high to recommend it without a doubt.
