Thermaltake Tower 900 Review – Worth Buying in 2021?

While buying Thermaltake Tower 900, I was thinking what exactly is this?

A fish tank or a case. And that is because of its huge size. Tower 900 has a height of 30 inches (2.5 ft) approximately.

That’s quite an enormous size and glass on three sides makes it look like a fish tank. Thermaltake, the company behind this device is renowned for producing some really solid cooling systems.

Most of us tend to buy the smaller cooling system but Tower 900, though quite high, isn’t a bad choice either especially when it makes use of its size in adding more add-ons.

The design of the Tower 900 is a result of a collaboration between Thermaltake and Watermod France. The company describes its product as:

Glasses are now in trend and Tower 900 is equipped with 5mm thick glass on three sides-left, right and front.

As explained above, it is 30 inches high and 17 inches wide. That’s quite the size of your showcase. What really makes this device spectacular is that it can be defragmented into different parts. You can remove the tempered glass and almost every part of this tower.

The case weight around 25 kg. Available in black and white, top of the tower features I/O ports. There are four USB ports. Other than that, we have a reset button and microphone jack. The button on the right is a power button which is really tactile.

Glasses are fitted using screws into dedicated rubber grommet holes so the glass doesn’t get scratched. Storage capacity is approx. 150 liters, one of the largest as compared to its competitors.

Now let’s investigate the inner portion. The PC case has two sides, one for the pump and one for the reservoir. As far as my opinion is concerned, I recommend using the left side for the GPU loop and the right one for the CPU loop.

Now that’s what I missed. There are two loops, pink and blue. Pink one goes to GPU and blue goes to CPU. You can interchange them because the left and right sides are the same and have equal space.

Thermaltake logo is featured at the center just below the drive bays, each of them is three and half-inch long. Key features of this device are as follows:

  1. Superior Expansion
  2. Unparallel Cooling Ability thanks to multiple fans.
  3. I/O panel on the top for smart control.
  4. Symmetric Dual Loop System to cool the liquid.
  5. Compatibility of a wide range of fans and radiators.
  6. Attractive thanks to tempered glass.

The bottom line is that Thermaltake Tower 900 might be a large big fish tank but reasonable price out-speeds that fact. You can grab it from Amazon here.
