Cooler Master Silencio 450 Case review

Today we are going to take a look at a computer case named “Silencio 450” from Cooler Master.  Cooler Master is known for their high quality products that are often low-noise.  I myself am very interested in and attracted to low noise products and am excited to get right on this case and test it out!

The Product:

Cooler Master Silencio 450 Case Package

The Silencio 450 case comes in a white-lilac box which has a picture of the product printed on it. Opening the cardboard box was easy and inside we found the case well packed in order to avoid any damage during the transportation.

This case is classed as a mid-tower case but it is a bit smaller than the usual mid-towers nowadays, and it´s also smaller and lighter than its mid-tower brother “Silencio 550”.

Cooler Master Silencio 450 Case Accessories

Inside the box we find the actual case and the manual. The other accessories provided, besides the manual, are placed inside the computer case. Accessories include: a manual, bags of screws, stand-offs, buzzer, dampening pads for the PSU, nut, a PC speaker, two expansion-slot covers and cable-ties. The PSU dampening pads are used for preventing vibrations in the case. I would’ve liked it if they included re-attachable covers for all seven expansion-slots, not just two.

  1. ” The two other 120mm fans are located on top of the case meaning that you
    can even isntall 120mm x 240mm water cooling radiators in the P280.
    This is a feature which I’d like to see available in more cases in the
    market! ”

    After reading this; it would have been nice to have actually seen what kind/ size (e.g. thickness) of radiator would fit in the Antec P280, my guess would be a slim 240mm (e.g. XSPC RS240).
