1. Cooler Master Silencio 352 – $55

Cooler Master Silencio 352 Silent PC Case

Cooler Master have long since been on top of the PC case hierarchy, their cases have a lot of thoughtful planning, even on the lower end.

The Silencio 352 is categorised as a “Mini-Tower” (17.8 x 7.8 x 14.9 in), making it perfect for those short on space. This small size also means there is only support for mITX and Micro ATX Motherboards.

As the name may suggest, this case was designed from the ground up to be quiet. The Silencio has foam padded front and side panels to help dampen noise. This doesn’t mean that airflow is an afterthought, with support for two 120mm front fans,  a rear 120mm fan and another 120mm fan for the top. It can even house water cooling systems with radiators up to 240mm in length.

The Silencio can support graphics cards up to 14 inches in length and house up to 3 3.5” drives and 4 2.5” drives, giving plenty of room for HDDs and SSDs. There is even room for a 5.25” drive behind the front door panel, which is good for a disc drive of some sort or a fan controller. There is room for a CPU cooler of up to 6.1 inches.

The Silencio can easily house a powerful PC with no compromises, there may be little room to play with but the clever design helps get the most out of the space. For just $55.99, this is a great small form factor silent PC case.

2. Corsair Carbide Series 100R Silent Edition – $65

Corsair Carbide Series 100R Silent Edition PC Case

Corsair is another big player in the field of PC cases, many people trust Corsair and for good reason as much of the time they hit it out of the park when it comes to the quality of their products.

The 100R Silent Edition is a mid-tower case (7.9 x 18.5 x 16.9 in), giving a good balance of size and performance. This case is certainly designed to be more subdued, to help it fit in rather than to stand out. Making it a good choice for a media centre. The 100R Silent Edition supports ATX, Micro ATX and Mini-ITX motherboards.

What makes this 100R a “Silent Edition”? Firstly, the inclusion of noise isolating materials in the side panels helps to keep the noise down and a 3 speed fan controller built into the back of the PC; the latter being something you don’t see very often, especially on a case as cheap as this. The case supports two front 120mm or 140mm fans and the rear takes one 120mm fan, giving the case a lot of potential for great cooling.

There are four storage bays, each supports both 3.5” and 2.5” devices allowing you to tailor the storage capabilities to your needs. There is support for GPUs up to 16.2 inches and space for a CPU cooler of 5.9 inches.On the front panel there are two USB 3.0 ports. There is room also for two 5.25” drives.
