Corsair Crystal 680X RGB Review


For the past few years, RGB lighting and tempered glass were considered as the primary trends when it comes to PC cases. With that, it is safe to say that the Crystal series from Corsair is one collection that completely sports these popular features.

Their latest Crystal 680X RGB appears to be no different for that matter. It sports a combination of side panels made from tempered glass, as well as three LL-120 RGB intake fans at the front part of the PC case.

The Crystal 680X RGB appears to be highly similar, yet larger than Corsair’s ATX 280X. It also has more breathing room for a wide collection of excellent RGB hardware. And with the presence of dual chamber design, things will be much easier for you when it comes to concealing cables; it also sports a lot of tempered glass, the RGB fans, plus the option of vertically installing your GPU which, obviously has a lot of emphasis on  aesthetics.

On the Crystal 680X RGB, you will find enough room for various fans and radiators to keep all the components cool. There are also a couple of tool-free drive mounts that offers you enough space for a total of seven drives which is very convenient.

When it comes to the price, the Corsair Crystal 680X RGB does not come cheap, so is it worth purchasing? Let’s go and find out.

Corsair Crystal 680X RGB Review – What’s in the Box?

Just like always, we’ll start off with what’s inside the package of the Corsair Crystal 680X RGB. The box clearly stands for the Crystal 680X RGB and it’s a simple yet nice packaging from Corsair that immediately catches your attention. It’s a strong and sturdy box, so you’ll know immediately that the company ensured that the chassis is protected from unwanted damages during transit.

Corsair packs this PC case in their signature brown box where the front displays an illustration of the chassis and the company’s name on the upper left corner of it. Below the image, you will find a thick black strip that displays the model of the chassis, which is the Crystal 680X RGB.

At the back of the package, you will find a diagram of the chassis where a list of its specifications are set on the smaller panels. To easily carry the product, Corsair also ensured to leave carrying holes on the box which is really convenient.

Inside, there are two thick and sturdy Styrofoam spacers present, which is necessary to keep the Crystal 680X RGB in place. There’s also a thin cloth bag that safeguards the chassis from fingerprints and scratches.

It’s actually nice that Corsair ensures the safety and protection of their products, since the Crystal 680X RGB didn’t have any noticeable scratches, fingerprints, or dents on it. For added protection, they also included plastic wrapped on all vital segments of the chassis such as the glass portions of it.

Along with the Crystal 680X RGB from Corsair, other accessories that you’ll find in the package include a set of assorted screws, a manual, a good supply of quality cable ties, and a magnetic dust filter which is for the top part of the chassis.

The Product

Corsair Crystal 680X RGB Review

The Crystal 680X RGB that we have is painted white, inside and out. The chassis sports a plastic and steel construction combined with tempered glass panels on three of its six sides. This PC case features the real dual compartment design where ⅔ of the chassis is concealed by the previously mentioned tempered glass panels, and the last third with steel.

Its tinted tempered glass panels are all raised to allow proper airflow, utilizing the extra longer screws and spacers between the top of the chassis and glass panel.

Directly under the top-most tempered glass panel, you will find mounts for three 120 / 140 millimeter fans; there is also a magnetic filter included in the Crystal 680X RGB’s package. Along the corners of the steel part that is closest to the tempered glass panel, you will find a pair of USB 3.0 ports, a microphone / headphone jack, USB 3.1 Gen 2 Type C, plus the reset & power buttons.

The smaller PC case from Corsair, the Crystal Series 280X, didn’t come with the rubber-coated locating pins. These were necessary for full coverage tinted, tempered glass side panels to safeguard the chassis from accidental drops.

What’s good is that the company remedied this particular situation and decided to include hinges to the Crystal 680X RGB’s tempered glass side panel. This chassis also makes use of solid magnetic latches on the front portion, providing you with easier access to the inner part of the chassis.

For added convenience, the side panel can be detached from the case simply by lifting it up then away from the hinges. Its simple steel panel located on the opposite portion features a filtered hole that is large enough for added ventilation; in addition, it is secured using captive thumbscrews which makes it better.

Along the back of the Crystal 680X RGB, you will see a total of ten expansion slots: namely two vertical and eight standard ones. There is also a gap for those bottom-mounted PSUs located on the secondary section, plus an exhaust fan mount that is fixed with a 120-millimeter fan.

There’s also a huge plastic mesh filter that conceals the two primary mounting locations found on the bottom part of the chassis; it is about ⅔ of an inch from the desk expanse to allow adequate air intake.

Each intake fan mounting area is covered by washable filters to prevent most dust and dirt particles from entering the system. The side, top, and front filters are linked using magnetic seals on the edges, while the bigger filter located at the bottom comes with a slide-out plastic filter.

Do take note that compared to the 280X, the Crystal 680X RGB’s front panel does not easily pop off to provide you access to its intake filter. Instead, you will need to remove the radiator mounting bracket’s thumb screws to properly pop out the filter.

This may be a bit more tedious in general compared to just removing the filter from outside, however, it does give you much cleaner lines on the front part. Whether you give importance to slightly better aesthetics than convenience, it all goes down to your personal choice and preferences. Yet if you are someone who lives in a dusty area where you’ll need to regularly clean the intake filters, it can be troublesome to remove the screws and case every now and then.

Now for the interior of the Crystal 680X RGB: with its front magnets and rear hinges, the tempered glass side panel acts more like a door and it is extremely easy to work with. Yet if you take a look at it, the same mechanisms were not applied to the other steel panel; and instead, you will be relying on thumbscrews with a rounded hinge design. It’s quite good that Corsair opted for this, since getting things back in place will be easy enough.

Its dual chamber design, where the primary elements are displayed on one side, keeps the slightly hidden ones completely out of view; these include the cables located on the other side.

The primary chamber of the Crystal 680X RGB comes with a pre-installed motherboard mount such as a lengthy middle one that is used for tethering the board as you reach out for the first present screw.

If you plan to vertically install your graphics card, just remember that it will be floating at a certain distance from the case’s floor. Don’t worry though, since we did find it to be secure enough even if you use it with something bulky like the RTX 2080 Ti.

This is also the area where all the fan mounts can be found. Working with the rear, roof, and the bottom parts is quite simple enough, while its front bracket can be internally detached from the chassis using two thumbscrews. These are really fastened, so you’d really need to have a screwdriver on hand.

Still, it lets you clean the magnetic dust filter and service or install the fans, as well as the radiators without having to yank-off the external glass or front panel. We were quite surprised about realigning it since we were expecting it to be fussy and troublesome; it’s a good thing that it wasn’t.

When it comes to the radiator compatibility, the integrated fan mounts allow 360 / 280 millimeter support, up front. For the bottom and roof mounts, these can be equipped with either the 240 or 280 millimeter types. As a standard, the rest of the hardware will provide you with the amount of clearance the areas have.

Let’s now shift to the expansive opposite chamber: the PSU is provided with small pads that it can rest on, as well as a moveable bracket that aids in securing and tightening it, depending on the length.

Above this, you will find two drive cages: one is dedicated to a 2.5-inch SSD that has four mounts present, and another that can accommodate a total of three 3.5-inch or 2.5-inch drives. Trays that are available on the latter are made from plastic and appear flimsy, but they’re quite tough and can be removed easily; plus, they also come with pins to secure the tool-free and rubberized sides of the HDDs. Generally, this is to absorb the vibrations that may be present.

Lighting Node Pro

This is actually included and fixed to the motherboard’s rear, and is powered using a USB 2.0 header. This is how it communicates and interacts with the iCUE software. When it comes to the controller, it has two unique channels where one is left ripe and unoccupied for expansion, while the other links to the fan hub.

All the three LL120 fans’ RGB cables are linked here, leaving a total of three for spare. This fan hub is powered separately by the SATA connection, and the fans will also require power with the help of 4-pin headers since the hub is mainly for lighting.

We think that it would be even better if there was a PWM fan hub, yet we understand that Corsair was focusing on the lighting for their Crystal Series. So with the Lighting Node Pro, plus the trio fans are a great addition as is, so we’re really not complaining.

All of the available I/O cables sport a nice black sleeve to lessen their visibility; also, there are a lot of routing holes with grommets that are equipped on almost all of them. We like these grommets since they’re really secure and don’t really move out of place which is great.

So with all that space in the secondary chamber, you know all too well that it’s the best area to stash everything, close the side panel, then admire what you’ve built.
