Thermaltake Tower 300 Micro Tower Chassis Review

Now the Tower 300 may be a Mini/Micro ATX case but it is still a tower! At 551 x 342 x 281 mm (22.5 x 14 x 11.5 inch) this case is definitely bigger than it looks.

It’s simply impossible to review the Tower 300 without stopping to admire the unique design. The three-window setup is just the tip of the iceberg of what makes this case special. If you are looking for a standard build, best skip to the Tower 200 or bump up to the Tower 500 if you need support for a full sized motherboard.

Each of the three windows is slightly tinted and yes, they do all come off for ease of installation. Controls are on the angled top panel making it easy to access things from both a desk and floor installation. The controls from left to right: Power and activity lights, power switch, reset, HD audio I/O, two USB 3.2 and a USB 3.2 (Gen 2) Type - C port.

From the back we have a large removable panel with a magnetic dust filter. Removing this panel provides access to the power supply (PSU) mounts. The max length for your PSU is 220mm.

Snapping off the top panel provides a closer look at the two included 140mm exhaust fans. Both of these fans are the Thermaltake CT140 fans mounted on Anti-vibration mounts. These fans are available with RGB but the included fans are the standard blacks.

Removing the glass panels is pretty easy if a bit nerve racking the first time! The center panel uses a push release at the top to open. The two smaller side panels use a set of tension fasteners and simply pull forward.

The motherboard will be installed with the back surface pointed up with cables running through the large rubber grommet at the bottom or out the top and towards the back.  Removing the top fan mount via two thumb screws provides access to the back of the PCI slots and any cables that will need to be run out the back for monitors and such.

With the back panel removed we have access to the back of the motherboard through some additional venting.  One advantage of the shape is the almost 1.5 inches of space in the back for cable management. Two drives can be mounted on the removable mesh,

Both of the vented side panels are attached by magnets and have their own mesh dust filters. The left side will be the venting for your video card solution of choice and supports cards up to 400mm without power cover and 280mm with.

The right side provides mounting for additional fan support or a radiator. The options are quite expansive for a case this size supporting solutions from 1 x 120mm to 1 x 420mm.  This case is just begging for a well-lit water-cooling solution or all in one CPU cooler.

The diversity of panel fastening solutions is interesting and shows the design team really thought out the choices based on the design. I can assure you everything fits like a glove with no concern of something coming loose.

The bottom or basement area houses the power supply but also provides additional mounting for another hard drive on the right side. Another 120mm or 140mm can be mounted on the top of the basement.

The bottom view shows the large feet for the standard vertical orientation to aid your power supply with airflow. A large mesh dust cover protects the entire bottom surface.

A removeable panel on the front of the basement is removable to support the optional LCD display kit, sold separately.
