The Redline RL04 is a mid-tower case from SilverStone targeted to users on a budget, costing only USD 53. Yet, it brings features usually only seen on more expensive models. Let’s see what the RL04 has to offer.

The left-side panel of the RL04 is meshed, supporting two 120 mm or 140 mm fans. The case comes with a magnetic air filter for this mesh. See Figure 4. However, this filter is not a perfect fit. As you can see in Figure 5, it is a little bit bigger than the place where it is supposed to be installed. As you can also see in Figure 5, the filter that came with our sample was a little bowed. According to SilverStone, this may happen in places that are too dry. Because of this, the filter wouldn’t stay in place, sliding down as shown in Figure 6.
