The 3R System T100 Valkyrie has 10 5.25” covers, but it actually has only three 5.25” bays. (One of them can be converted into a 3.5” bay.) The other covers are used by two 120 mm fans. These covers are vented, but they don’t have an air filter. There are, however, air filters for the fans, which are removed from the left side of the front panel, as you can see in Figure 5.

The two 120 mm fans available on the front panel glow in blue when turned on, but the manufacturer doesn’t state their main specifications. They are connected to an individual three-speed controller located at the top panel.
