Most of Thermaltake's Spedo chassis is made of 0.8mm SECC steel, but the front bezel is composed mostly of a metal mesh. Behind the metal mesh is some material to act as a dust filter. There are seven 5.25" drive bays with four on the top and three on the bottom. Between the external drive bays are the six internal 3.5" drive bays. Between the 3.5" drive bay cage and the bezel is a 140mm LED intake fan. These bays are tool-free. On the right hand side of the front bezel is the power and reset switches. Located on the top of the chassis are two USB 2.0, one eSATA, and two audio ports. On the top of the chassis is more metal mesh for the 230mm exhaust fan.
The side panel of the Spedo Advance Chassis contains a 230mm intake fan along with an acrylic window and mesh area near the hard drive cage. This 230mm side fan doesn't directly connect to a conventional 4-pin molex connector but interfaces with the chassis through a contact area near the edge of the panel, which makes it ideal not having to worry about connecting/disconnecting wires when opening this chassis.
At the rear of the Thermaltake Spedo Advance Chassis is the I/O panel, eight expansion slots, dual 120mm exhaust fans, two holes for water-cooling tubes, and the power supply mount at the bottom of the case. At the bottom of the case are four retractable feet.
Opening up the case the Advance Thermal Chamber 3 (ATC3) and Cable Routing Management 3 (CRM3) systems are visible along with the independent adjustable fan bar and other advanced features. The Advance Thermal Chamber 3 is removable so that components can easily be installed into the system and then reinstalled later. Most of the features for this case are also tool-free. Behind the motherboard panel is the Cable Routing Management 3 system, which works quite nicely to effectively manage the cables. While this case is quite large, it can only handle ATX and micro ATX motherboards, but not Extended ATX.
