Building a PC inside the Silencio 652S is an uneventful process—for the most part.
The case is relatively roomy, and all of the various bits and pieces fit together without coaxing. I did need to install motherboard standoffs myself, though, and as I noted on the previous page, solid-state drives can't be snapped on. They have to be screwed in.
I didn't hit any snags until I got to cable routing. Therein lies what, in my view, is the Silencio 652S's biggest weakness. The clearance behind the motherboard tray is just too tight.
Routing the cables through the holes around the motherboard didn't take too much work, although the holes are somewhat small and close to the circuit board. Once the cables poked out on the other side, however, I had to route them very carefully so as not to prevent the side panel from sliding back on. I was pretty much forced to use cable ties, which I usually dispense with for case reviews. Then, even after careful routing (and re-routing, and re-re-routing), the side panel wouldn't go on until I laid the case flat on its side and pushed a little.
Perhaps I could have arranged the cables in a better, slightly more efficient way. The picture above does show some of the SATA and power cables overlapping. That overlap was difficult to prevent, though, since the system's Blu-ray drive needed its own SATA power lead. Keep in mind that this build only has one hard drive, one SSD, and a single graphics card. A beefier storage setup and multiple GPUs would entail more data cables and power leads, at which point overlapping would be all but unavoidable.
I was able to mitigate the problem by letting more cables poke into the main compartment than I usually would, without putting them directly in the path of airflow. Still, I don't recall ever having to work so hard to get cables organized in an enthusiast enclosure of this caliber. Even the $60 Carbide Series 200R from Corsair was better in that department.
I suspect part of the problem may lie with the foam on the right side panel, which effectively reduces clearance by a millimeter or so. The motherboard tray is awfully close to the edge of the case to begin with, though. Cooler Master could easily have added another quarter inch of space there without increasing the Silencio 652S's bulk by very much. I'm not sure why they didn't, because this case is clearly designed to house large storage arrays. What's the use of all those drive bays if space for power and data cables is so limited?
