Cooler Master Silencio 452 USB 3.0 Black Silent Mid Tower Case, 2x120mm Silent Fans + SD Card Reader w/o PSU is rated 4.6 out of 5 by 5.
Rated 3 out of 5 by from Many good features, but . . . . . . the interior is a bit flimsy, constructed of very thin metal which flexes alarmingly. My particular gripe is that with the specific HDD I chose for this build, (WD Caviar Black, 2TB) (1) the mounting holes do not line up with the plastic 'tool-less' mounting gadgets, and (2) there seems to be a particular resonance problem with the combination of this case and this HDD, which results in a loud hum when the drive is running. Maybe a particularly vibration prone drive? It's better in a different case. Overall this case gave me the impression that a lot of attention had been given to keeping the costs down without compromising on quality; but here and there compromises have in fact been made.

Rated 5 out of 5 by from Solid Case Good mid range case which is very quiet in normal operation.

Rated 5 out of 5 by from Good value case, lots of features This is a great case for system builder. Good quality and great price. Case has: No sharp edges Tooless design Lots of options Comes with 2x 120mm fans Plenty of room Loads of spare screws Down sides: Rear cover is tight to cables run through cable grommets (you need to be tidy with your install) Front door can't be removed Needs better instructions Notes... I fitted a cooler master sidieon 120 CPU water cooler, moving the rear fan to the front and fitting radiator to rear fan location. You can only fit the rear part of CPU mounting plate by removing the MB. And the screws that hold the rear fan in your cant use in the front location... I was lucky my cooler came with spare/option fab screws that fit the front but are too long if you want to use all the HD slots.

Rated 5 out of 5 by from Great Case It is practically silent despite the 2 large cooling fans and has all the case inputs you could require!
Date published: 2015-02-09
Rated 5 out of 5 by from Pocket Money Case With Some Class.... This case fits my budget and holds the ability of a good i5 system with both a simple but classy design and enough room for my needs....with todays products getting smaller this type of case will become very popular for those who have slightly smaller pockets....the only improvment would be a side window to show of your design but perhaps the future will supply that and Coolermaster will reap the benifits....

Questions & Answers

Water cooling?

Does this case support the cooler master sidieon 120 v.2? Also, will the internals get really hot due to the lack of ventilation?
Asked by: KlaUs
Hello, This only supports the Seidon 240M. Temperatures would depend on the airflow in your set up. Thanks,

Can the door be mounted either hand?
Asked by: TheGardener
No, and it's not removable either.
