There are 2 included fans - Fractal Design Dynamic GP14 fans rated at 1000RPM. There is 1 located in the front, and 1 in the rear.
In total, there 2 are fan slots in the front, 1 in the rear, 3 on top, 2 in the bottom, and 1 on the side. These provide plenty of options for fan placement.
The R5 goes for the minimal look, and it nails it. There isn't even any branding on the exterior. Both sides are completely flat slates, and the minimalist design is only broken on the top with I/O up front and 3 removable panels (for cooling solutions).
It's best to keep the 3 top panels right where they are - removing them will greatly increase the noise output of the machine, as well as break its dust-seal.
While not exceptional, the stock cooling properties of the case as well as the noise output beat average scores slightly when a similar setup is used in a different case. The GPU was a bit warm, while the CPU was considerably cooler.
If you overclock, then it gets very noisy and warm - much more than other cases.
There's plenty of room for all the components you could want. Just about any GPU will fit - even some extra long cards - and there's even room for most liquid cooling systems.
You won't need any tools to assemble the Shinobi XL other than a screwdriver. The drive bays have pegs that bend, holding the drive in. The PSU (power supply unit) is also a breeze to install with rubber feet that the PSU rests on helping to align it properly.
There isn't enough space along the routing lines to fit all the cables needed. There is space in crevices, however those are nearly impossible to access.
The case is large, which means there is lots of room to build and route cables. You also won't be restricted much by size, meaning you won't have to prioritize size over cost or performance. There are virtually no sharp edges that could cut corners (or fingers).
The interior of the case is extremely ridged, which is needed because the windowed side doesn't offer any structural support. It doesn't flex, and feels sturdy.
On top of the case there is room for a liquid cooling radiator (up to 360x140mm), and near the top of the rear of the case there are holes for cooling hoses.
There's a stand on the bottom of the case (perfect for a liquid cooling radiator) that can't be unscrewed while inside the case (the front panel of the case blocks the screws).
If you intend on connecting some of the cages, be warned that the paint will flake off easily. This making adjusting the internals of the case more difficult.
