Summary

• Corsair 3500X is a budget-friendly version of Corsair 6500, offering great value and impressive airflow for PC builders.
• With support for E-ATX motherboards and plenty of fan slots, Corsair 3500X is easy to build in and offers a sleek design.
• While cable management can be improved, the Corsair 3500X ARGB is a well-designed mid-tower case with good thermals and functionality.

There are a plethora of choices for a PC case when building a system. The Lian Li O11 Dynamic opened a portal to a realm full of similar-looking "aquarium"-styled cases and Corsair is out with yet another. This is not a negative on the company as I'm personally a fan of this form factor and enjoy seeing all the different takes and iterations from various brands. The Corsair 3500X is essentially a cut-down and more affordable version of the Corsair 6500 with a single chamber design.

Corsair has also implemented support for reverse connector motherboards such as the MSI Project Zero. PC cases such as the Corsair 3500X are all about the design and complete look. It's a statement and not simply a PC build, but thankfully the company didn't forget about function as well as a healthy dose of form. There's solid cable management, clearances, I/O, storage mounts, and plenty of points to install up to eight fans. Building a PC inside this chassis is simple and enjoyable, something that cannot be said for every case under $100.

Price, specs, and availability

The Corsair 3500X range of PC cases starts from $90 for the base model with no cooling fans included. This is a great choice for those with fans and those who wish to buy aftermarket solutions. The next step up is the Corsair 3500X RGB, which is the model we're reviewing today. This costs $110 and comes with three pre-installed Corsair RS120 RGB fans on the front-side intake bracket. Then there's the range-topping iCUE 3500X RGB, which (as the name implies) has three iCUE LINK RX120 fans and a pre-installed iCUE Link System Hub for controlling everything.

Corsair isn't known for making affordable PC cases, so it's good to see yet another sub-$100 option available for system builders. All three versions of the Corsair 3500X are available in white or black and have identical specifications. They all support E-ATX motherboards, GPUs up to 410mm, PSUs up to 180mm long, and can hold a CPU cooler with a maximum height of 170mm. Two 2.5-inch and two 3.5-inch drive slots are present for storage, though there's a good chance you'll be using the M.2 form factor with modern motherboards.

Although it supports motherboards up to E-ATX, it's not a massive PC case, measuring 506 x 460 x 240 mm. You won't have trouble placing this desktop PC on or below your desk.

Design and features

Form and function

Unboxing the Corsair 3500X RGB was easy as the case is shipped inside a single cardboard box with standard foam packaging. There's a small manual present with the chassis that contains basic details on the case, but a full manual is available on Corsair's website. This is seemingly the way forward for most brands to save money and paper waste. Downloading a manual on your phone takes a few seconds and isn't an issue in today's world. Once the case has been removed from the box and protective wrapping, it's clear to see that this is a good-looking chassis.

It's a basic design but looks sleek, especially in black with the slightly smoked tempered glass panels.

The front panel is a single pane of tempered glass and so too is the left-side panel. These two windows provide an uninterrupted view of everything contained within. The top panel has the front I/O, consisting of a single USB-C 3.2 Gen 2 port, two USB-A 3.2 Gen 1 ports, a 3.5mm audio jack, and power and reset buttons. This is joined by a 360mm radiator vent for up to three 120mm fans. The right-side panel also has ventilation for up to three intake fans and a 360mm radiator, providing ample customization for cooling.

Seven PCI slots are on the rear with a single fan mount. It's your typical ATX case affair but without any vertical GPU support, unless using an aftermarket solution that secures itself to the horizontal PCI slots. It's a basic design but looks sleek, especially in black with the slightly smoked tempered glass panels.

Building a PC

Easier done than said

Building a PC should be straightforward for most ATX cases, though I've seen some chassis where it's considerably more difficult — I'm looking at you, Vetroo K1 Pangolin. The Corsair 3500X is a standard affair and as such is just as easy as any other Corsair case to build your dream PC inside. Removing the top, front, and side panels is as easy as pulling them away from the main frame. They're held with small clips and you'll have unlocked incredible all-round access to the Corsair 3500X ARGB once all three panels have been extracted.

A dust filter is present on the top, side, and bottom panels to help keep the insides of the 3500X clean of particles. Even with the two glass panels removed from the frame, there's barely any flex in the steel, which I've not seen in other cases that do not have a support column between the side and front glass windows. Considering this is a case that starts from less than $100, that's a sign of good design and construction. You can feel the quality throughout each panel. Good attention to detail only improves the value offered here.

Although Corsair makes some marketing noise about supporting reverse motherboards, the cable management could be improved.

The PSU shroud is large enough to fit almost any power plant. I opted for the incredibly powerful NZXT C1500 Platinum PSU. It fits snuggly into the dedicated area without cramping the cables. The process of installing the motherboard was as easy as any other ATX case, though you may find the Corsair 3500X more enjoyable to work with thanks to the all-around access. Cabling is managed behind the motherboard tray and although Corsair makes some marketing noise about supporting reverse motherboards, the cable management could be improved.

There's ample space for installing an air cooler like the be quiet! example we used in this review. An AIO from Corsair or any other reputable brand will also fit fine. Two 360mm radiator mount locations are at hand.

Performance

Good airflow for lower temps

Running an Intel Core i5-12600K and GeForce RTX 3060 Ti inside the Corsair 3500X ARGB, I experienced no trouble running synthetic benchmarks and some PC games. Though the processor doesn't get too hot, it can still kick out a considerable amount of heat, especially with the GPU running at full load. Using the three preinstalled Corsair fans in the side panel and the single blower attached to the be quiet! CPU cooler, temperatures were as expected with such a configuration. Adding more fans reduces temperatures as we've seen with other cases using the same form factor.

The Core i5-12600K happily ran at sub-70C when running heavier loads and the GPU barely made any noise in demanding games.

Should you buy the Corsair 3500X?

You should buy the Corsair 3500X if:

• You want a good-value PC case with some premium features.
• Don't mind spending $100 on a sleek-looking chassis.
• Have a high-end CPU cooler or AIO liquid cooling solution.

You shouldn't buy the Corsair 3500X if:

• You want to buy a custom open-loop water cooler.
• You want a PC case with the highest airflow.
• You want a dual-chamber PC case.

I recommend shortlisting the Corsair 3500X ARGB. This is a well-designed and built mid-tower PC case that offers a premium look and feel without sacrificing function over form. Thermals are kept in check by the eight available fan slots and if using active CPU cooling, you can achieve good airflow with little impedance. Building a PC inside the Corsair 3500X is a pleasant experience not met with frustration, even if you happen to be using a standard motherboard with headers facing upward. Even larger GPUs and PSUs can be installed inside this case without any trouble.

If you are in the market for a slightly smaller and cheaper Corsair 6500, the Corsair 3500X is a must-buy.

The Corsair 3500X ARGB isn't for everyone. If you've grown tired of the O11 Dynamic form factor, I would look elsewhere as this is essentially the same deal but with a single chamber. The PSU shroud does help break up the design unlike the Corsair 6500, but the two glass panels and use of the side panel for bringing cool air into the chassis will see your PC resemble countless thousands of other systems out there. If you are in the market for a slightly smaller and cheaper Corsair 6500, the Corsair 3500X is a must-buy.
