The Overseer RX-I is the latest full-tower case from Thermaltake. However, its physical dimensions are similar to mid-tower products from other manufacturers. Unfortunately, there is no official standard to categorize a case as full-tower or mid-tower. According to Thermaltake, they are saying this case is a full-tower model because it has four 5.25” bays, eight expansion slots, and supports E-ATX motherboards, even though the typical full-tower case looks bigger.
The left panel has a transparent window and a mesh with an air filter for an optional 200 mm fan.
