Let us now take a look inside of the Cooler Master Silencio 650 case. The Cooler Master Silencio 650 is also inside of the chassis completely black coated, whereby all plate edges are very well deburred, folded and rounded, so one can work thus without any lesion in this case. Like the previous Cooler Master Silencio 550 this Cooler Master Silencio 650 has also integrated many features to make the upgrade more easily.
Here you can see the large motherboard tray cut-out to mount a screwed CPU heatsink from the motherboard back side without removing the motherboard and the cut-outs with rubber seals to get the cables behind the motherboard tray.
Both upper 5.25″ drive bays are installed with an easy mount system Just slide the drive locking mechanism to Open …
… then insert the drive and slide the drive locking mechanism to Lock:
The lower 5.25-inch drive bay is pre-installed with a special HDD mounting frame as previously written, but it can be also used removed in case you want to install more conventional 5.25-inch drives.
3.5-inch drives are very simple to install as well with the sliding rails, we already know from some other chassis. Just put a sliding rail on the HDD screw thread …
… and insert them together into the 3.5-inch HDD cage. Just put a sliding rail on the HDD screw thread and insert them together into the HDD cage. At the end position both sliding rails will catch and hold the drive secure in the cage. Two of the bays have a PCB with a SATA connector at the end position. If you insert a hard disk in these two slots, you can select them with the HDD switch at the front panel.
For 2.5-inch drives or to screw a drive without the sliding rails, Cooler Master has integrated a 3.5″ to 2.5″ mounting frame.
And also for the front drive, Cooler Master has developed a special 2.5″ mounting frame. The 2.5″ mounting frames make sense, because nearly all PCs are equipped with minimum one SSD.
Here you can see the black coated slot brackets, which has thumbscrews for easy and fast card mounting. The middle drive bay cage can be unscrewed by the way to provide enough space for one or two long graphics cards.
Over the slot brackets is a 120mm fan integrated to offer a direct circulation of the warm CPU air.
In the front of the case are two additional 120mm fans integrated to blow the fresh air through the HDDs into the enclosure.
All plugs of the I/O panel connectors, both LEDs, power button and reset button are well labeled and the Power-LED pins are seperated, because some motherboards have different pinouts. The internal USB connector for both USB 3.0 ports, for both USB 2.0 ports, the SD-Card reader and the connector for the 3.5mm audio plugs are each build in one block, whereby the audio connector offers an AC’97 and a HD audio pin allocation. So it is not necessary to connect each pin to the motherboard. Nevertheless one should compare the pinout of the plugs with the motherboard manual before the installation.
Result and general impression of the Cooler Master Silencio 650 Case …
