Montech KING 45 PRO Case Review

PC cases are often treated as an afterthought, but they’re one of the most important parts of any build. A good chassis isn’t just a box to hold your components – it determines airflow, thermals, noise levels, upgrade flexibility, cable management, and even the overall personality of your setup. Whether you’re a first‑time builder, a seasoned enthusiast, or someone shopping for a prebuilt, understanding what a case offers (and who it’s designed for) can make the difference between a smooth, enjoyable build and a frustrating one.

In this review, we will explore the Montech KING 45 PRO, released in October 2025, alongside three other cases: the Montech KING 15, the Montech KING 45, and the Montech KING 15 PRO. All four models build on the foundation of the original KING 95 PRO, refining the formula in different ways to appeal to builders with different needs – from compact‑case fans to airflow‑focused power users. We’ve also got a full build coming up using the KING 45 PRO, so if you want to see how it performs in a real‑world setup, keep an eye on the site.

Specification

The Montech KING 45 PRO is born of the KING legacy created by the Montech KING 95. Unlike the KING 95 model, the Montech KING 45 is available only in black and white, whereas the KING 95 is available in black, white, blue, and red. This mid-tower chassis can house ATX, Micro-ATX, and Mini-ITX motherboards, and it stands 462mm tall, 245mm wide, and 450mm long. Montech provides an adequate set of front I/O ports: two USB 3.0 Type-A ports and one USB Type-C port, along with a combined headset jack and buttons to control the case’s lighting and power.

The chassis comes with 7 horizontal PCIe slots that can be swapped out to enable vertical GPU mounting, and the clearances defined by the KING 45 PRO allocate 435mm for a graphics card, 187mm for a CPU cooler, and 180mm for a PSU. This chassis can accommodate up to two 4TB storage drives (two 2.5″ or two 3.5″).

With the Montech KING 45 PRO, the ‘PRO’ designation indicates that the model includes pre-installed fans, following the same marketing style as the Montech KING 95 and Montech KING 95 PRO, where the Montech KING 95 model did not include pre-installed fans. The 45 PRO equips three bottom-mounted 120mm RX120 PRO intake fans in an angled orientation and one exhaust 120mm AX120 PRO mounted on the rear of the chassis. These are powerful fans that can reach up to 1600 RPM, helping keep your PC’s temperature down. The angled fans’ purpose is to directly channel cool, fresh air into the graphics card, which seems like an added bonus feature.

Due to the KING 45 PRO’s thinner profile, relocated PSU chamber and glass front panel, there aren’t many mounting options for a radiator; it can support up to a 360mm radiator on the top panel and a smaller 120mm on the rear panel. Finally, the Montech KING 45 PRO has an MSRP of $119.99.

Montech KING 45 PRO Design

In structure, the Montech KING 45 PRO inherits the physical design language of the Montech KING 95, except with a smaller footprint. The case features a new 15° curved glass side panel, and the Front IO has found a new home, located at the bottom of the front panel. There is a minimalist ARGB trim running down the front panel of the chassis, which appears to have been refined as well.

Internally, there has been a slight shake-up with how the airflow functions and where the PSU is located. Montech appear to have jumped on the budding trend of angled bottom-intake fans.

These fans are equipped with a dust filter to protect your system. We hypothesise that the initial inspiration for this quite possibly came from the HAVN HS 420 VGPU case and the Lian Li O11 Dynamic Mini V2. The idea behind this implementation is to optimise air flow to the graphics card, which, in theory, makes perfect sense.

As mentioned above, the case comes with four pre-installed fans, configured for optimum airflow performance; what is special about these fans is that they actually have a specific blade geometry that pushes up to 10% more airflow into your system. At the same time, ARGB lighting transforms your build into a visual statement, glowing from every angle with vibrant, customisable effects.

Storage drives can be mounted on a tray that swings open for easy access behind the motherboard. This tray is secured with a thumbscrew, ensuring it remains stable during transportation.

Curiously, this chassis also supports reverse-connector motherboards, so it is worth taking an extra moment to plan cable and storage-drive clearances should you wish to combine them in your build. The case includes some tie-downs to help secure and manage cables; however, we feel there could have been a greater effort to provide dedicated routing pathways.

An included fan hub does offer some help with cable routing and power should your motherboard be lacking headers . The angled mounting of the hub, does further help to alleviate some of the teething issues but the cabling is still rather fiddly nonetheless, given the lack of dedicated cable routing.

Lastly, Montech has moved the PSU chamber to the front of the chassis compared to the Montech KING 95 and included an internal power cable extender to ensure cable length issues do not hinder your build’s success.

Air still draws in from the backside panel through perforated holes in the metal panel, allowing exhausted air to exit the system through the top panel. One thing to note is that the White variant of this case still has the cable, but unfortunately, it isn’t colour-matched.

Features We Like

Spacious Cable Management

There is roughly around 28cm of room behind the motherboard for cables, which is perfect given how bulky and obtuse they can be, not to mention fiddly. Even with the storage tray, there is still ample room. Overall, the internals could be tidier; the case would benefit from intentional and designated tie-down points or routing channels.

More Compact

We like that this case is a tighter iteration of the original model, and we also like the approaches Montech have taken to tackle issues before they happen, such as the suring thumbscrew for the storage tray and the provision of an extension lead for the PSU. These are quite thoughtful and offer some insight into the engineering behind the chassis.

Features We Don’t Like

Internal PSU Extension Cable is Black

It is slightly disappointing that the PSU Extension Cable is black in the white colourway, as it can be seen from inside the case and above the case through the top panel’s airflow holes. Why not colour match, especially since you can see the cable through the perforated top panel and from inside the chassis?

Not an All-White Case

When manufacturers advertise a product as black, it’s black – maybe a few silver screws here and there, but even those can be colour‑matched. With this case, the issue isn’t the main chassis; it’s the add‑ons. For example, the female end of the power supply plug on the rear of the white version is still black. It feels like a misstep, especially considering Montech took the time to colour‑match something as minor as the hard‑drive tray.

There are just enough black accents scattered around that the case never truly feels “all‑white.” Now, to be fair, I can see why this design might appeal to some people. Not everyone wants a completely white build. But for me, it’s a small gripe – you rarely see black cases with random white accents, so the inconsistency stands out. It’s not a deal‑breaker, just something that feels a little unfinished.

Minor Thermal Concerns

As with any wrap-around glass panel case, airflow concerns are important, as air may struggle to enter the case. This case is also a little bit smaller than usual internally, so it doesn’t leave much room to work. We’d highly recommend kitting this case out with a 360mm cooler and additional fans.
