Assembly

Installing the motherboard is quite straight forward using the pre-installed spacers and supplied screws. The full-size ATX board lines up perfectly with the forward facing edge of case, so those wanting to use wider boards will have to let that edge float a bit, but it could work. Adding a GPU is also as you would expect and the Palit GeForce 4080 fits easily with plenty of room to spare. Montech mentions that you can use an AIO in the side position and is mindful that such a setup could reduce the maximum possible GPU length to 275 mm. However, it looks like there should be enough room for a standard thickness AIO and long GPUs.


Adding a 2.5" drive to the swing open door is easily done, using the included screws. Alternatively, there is that tool-less spot on top of the HDD cage. Simply use the four skinny thumb screws and push the drive into the rubber ringed mounting holes. Plenty of friction is enough to securely hold the unit in place.


Adding a classic hard drive is tool-less as well if you are using the plastic trays. The drive just snaps into place and the whole contraption may then be slid right back into the metal cage from the back.


Long and powerful PSUs should easily fit within the King 65 Pro as well, as Montech mentions a solid 185 mm of room. Interestingly enough, this is specified as 190 mm on the King 95 Pro, which uses the same body, so it seems like Montech has tweaked this number. Regardless, even with the shorter spec, there are plenty of high-efficiency units that easily fit this. The PSU sits on top of the rubber lined support structure with its fan facing outward for direct access to fresh air, and is secured by four screws through the back of the chassis.


The 360 mm AIO has a ton of room all around, making cable wiring and connecting things to the top edge of the Motherboard a breeze. While you can remove the mounting frame, there is really no need with this type of setup thanks to all the space. That modularity will certainly come in handy with thick radiators or push/pull configurations, however.


With everything installed, the Montech King 65 Pro makes a good impression. Unfortunately, skipping the grommets on the openings really puts a dent into what the cable management could look like. Especially since we experienced their benefits in the King 95 Pro. Obviously there is the trifecta of ATX power, USB-C and USB 3.0 wiring on a tight bend radius on the right edge of the board, but that is always a thing with these type of case layouts. In the rear, the cable management is along the center with the Velcro strips. Note that we did not have to use a single zip tie but still have access to everything, incl. the side fans for example.

Finished Looks

When turned on, the Montech King 65 Pro looks nice, with the power LED lighting up at the center of the button. Unlike the King 95 Pro, which has a built-in ARGB element in the front, clear glass and twice the number of fans, this variant of the King series is a lot more muted. Those tinted glass panels are just tinted too heavily.


Looking at the chassis from the front or side, you can see the glow of your components but none of the design intricacies of your GPU, motherboard or memory for example. In the rear everything is where you would expect to see it from a sandwich style chassis and the steel panel on the other side of the King 65 Pro does give you a bit of a glow from the fans, and you can even see the SSD mounted as well. So, if your 2.5" SSD or PSU have ARGB elements, you will also get to see those from this angle.

Thanks to the built-in controller, you can toggle through an array of single and multicolored animations. There are also several solid color options with some shown below.
