Inside the Cooler Master Sileo 500 Mid Tower Case
After unscrewing the thumbscrews and sliding the door to the rear of the chassis, I flipped it around to get a look at what Cooler Master chose to use for sound deadening material. This "egg crate" style foam is a fair bit better at absorbing noise than say the flatter materials on the market. Cooler Master applies this foam to both panels everywhere it didn't get in the way of function or fit, aside from the inner front and rear panels.
With the panel out of the way, the Sileo 500 can show what the interior offers. With all the paperwork and miscellaneous hardware strewn about the interior looks a bit cramped, but everything inside shipped well and there were no casualties to any of the parts.
Once all the materials were removed the Sileo 500 opens right up, accepting both mATX and full ATX motherboards. All of the interior steel is chemically treated and left at that. This goes for the drive racks as well, of which both the 5.25" and the 3.5" drive racks use screw-less latches to mount all of your drives. The 5.25" bays use a mounted slide and lock type mechanism, while the 3.5" bays use rails that align in the side of the hard drive and then slide into the rack and lock into position.
Looking at the inside of the front from this angle gives a much better perspective on a few things. First, starting at the top and working my way down is the ventilated bay covers. These will allow for a bit of air to naturally pass through them. Removing them is the best option for maximum airflow. Dropping down to the 3.5" bays in the middle, there are two slots, but only one can be used as the other is used up by the front I/O panel's position in the front. Lastly, just to the left is where the wires pass from the LED and switch area. This placement helps to keep things tidy looking, as you will see soon.
Inside of the rear of the Sileo 500 there is the equipped power supply pre-installed with foam pads both on the support under the power supply and against the rear panel. Under the PSU is the 120mm rear exhaust fan that uses a unique mounting system which I will show more on in the hardware section. At the bottom are the seven clip-in expansion slot covers that are locked into place with a plastic screw-less clip. There is a tab on the side that when pressed allows the release of the covers so you may install your video, sound or tuner cards.
Laying the chassis on its back, I can show both the rubber feet on the bottom of the Sileo as well as the use of more sound deadening material in the top of the chassis.
Removing the rear panel of the Sileo 500 reveals, well, not much really. There isn't a hole for CPU back plates in the motherboard tray, nor is it removable, but this is a budget priced chassis so keep in mind; some customization may be needed. As far as hiding wiring, the tray is really close to the panel to maximize interior space, which leaves little room to run wires behind the tray. Creativity is the key to managing wires in this case.
