PC case design has reached a fascinating point where airflow-first enclosures no longer need to look like meshed-up monoliths. Endorfy, known to some as the rebranded SilentiumPC, has slowly been building a name for itself as a brand capable of delivering clean aesthetics without skimping on performance fundamentals. The brand realises its goal in Arx 700 ARGB, a mid-tower case that aims to deliver serious cooling potential while still looking good on your desk.

How we test and review products.
Despite the matte black version launching at the back end of 2023, the recent introduction of Arx 700 White ARGB gives the chassis a second wind, appealing to those who want a brighter, more open aesthetic. For £106 / €115, it’s aggressively priced, especially considering it ships with four pre-installed 140mm ARGB fans and a few quality of life elements missing on rivals of a similar cost.
Specification
At first glance, Arx 700 ARGB gives off familiar vibes: a high-airflow mesh front, tempered glass side that presents a window into your PC’s soul, and an open internal layout. What sets it apart is its ample volume for an ATX build. Endorfy has delivered a wide-body design with enough elbow room for fat GPUs, chonky coolers, and cavernous airflow paths.
Materials are exactly what you’d expect for a good chassis, chock-full of steel with good rigidity. There’s a bit of flex with the front mesh panel, but intentionally so. Its design filters dust without obstructing airflow and can only do so if made thin enough. Even with a bit of bend when I press down with both thumbs, it springs right back to how it was before.
The matte paint used on the black version is smooth and clean, resisting smudges well, while the newer white edition elevates RGB elements to a whole new level – colours simply pop more when surrounded by that icy tone. Credit where it’s due, though; the four 140mm fans Endorfy ships with the chassis come with white blades no matter the colourway, promising brighter lighting.

There’s a full-length PSU shroud at the bottom, ventilation cut-outs throughout, and dust filtering in every logical location. Front, top, bottom are all covered, though only the PSU filter slides out. The front panel is easy to remove without needing to tug forcefully, exposing a clean fan mount tray and magnetic mesh that’s particularly satisfying when piecing your build together.
Radiator support is generous. Both the top and front support up to 360mm rads, with enough room up above to prevent conflict with motherboard heatsinks. GPU clearance tops out at 410mm, leaving space for just about anything currently on the market, including the often huge GeForce RTX 5090.
Wider space comes with some caveats, such as creating a gap around the expansion slots. This is something we sometimes see on larger cases, such as Fractal Design Meshify 3 XL, but Endorfy’s solution is quite elegant. Rather than clip-on plastic you may inevitably lose, Arx 700 ARGB puts it on a hinge and clamps it with magnets. It’s the small touches like this that go a long way towards making the case feel more premium than its price would have you believe.
The tempered glass side panel mounts flush with the frame, and locks in place via two captive thumbscrews. There’s no hinge or guide rail, however, which can make popping it back on fiddly. Without alignment pegs or notches, it’s easy to fumble and makes for a smudgy mess when it comes to fingerprints. A cloth is essential, not optional.
Up front, you’ll find a slightly more comprehensive I/O panel than most chassis in that audio splits between individual 3.5mm mic and headphone ports, and there’s a dedicated lighting preset button. Otherwise, it’s your standard affair, including a USB-C port, two USB-A ports, and a power button that feels satisfying to press. There are cases twice the price out there that fail even this simplest of tasks.
Building
Endorfy opts for a classic but effective internal layout: a shroud hides the PSU and a 3.5in drive cage, with direct airflow across the GPU and CPU. Two SSD mounts sit behind the motherboard tray, and you can find two more in the board’s shadow since there’s no vertical graphics card support to get in the way. All told, you get support for up to six storage devices, which is pretty good for contemporary builds.
The first quirk I noticed when fitting our usual Intel Core i9-13900K build into the chassis was that the standoffs don’t support the same screws as other cases I’ve reviewed. This isn’t an issue as Endorfy provides everything you need to pin the motherboard in its bag of accessories and they’re as secure as can be, but it did make me take a step back from my usual process.
Another quirk is that the case’s I/O cables are jet black no matter which colour chassis you use. I’ve nothing against a panda theme but this takes away the choice for those seeking a purely bleached build when using Arx 700 White ARGB and there’s no way to change them from the user’s side.
Cable management is a mixed bag. There are plenty of grommets to slip even the thickest 24-pin cable through with ease, and the included Velcro straps keep it all tidy. I’m a particular fan of the single grommet on the PSU shroud, as this let me feed a 12V-2×6 cable adapter into my Nvidia GeForce RTX 5080 without the bulky eight-pin connectors poking through.
That said, you’ll have a challenge on your hands keeping the rear flush for the side panel to fit back on. With just 23mm of clearance, there’s no central cable cover or multi-channel system to neatly hide the mess. You’ll get it clean with patience, but the process isn’t as seamless as be quiet! Light Base with built-in routing trays or Meshify 3 XL with muscular clips holding everything in place. Still, at roughly half the price of these rivals, it’s hard to quibble with Arx 700 ARGB’s rear.
Four 140mm Stratus ARGB fans come pre-installed with the wiring already done and dusted, leading to a five-port lighting controller. I’d have liked to see more than just one free connector to add my own blowers, particularly as the max 1,200rpm speeds here aren’t enough to tame the might of a Core i9 when the CPU’s let loose. Thankfully, we live in the days of daisy-chained options, so nothing’s stopping you from filling the three 120mm fan slots at the top without stretching yet more wires to the front end. Besides, it’s rare we see a fan controller at this cost, let alone a fully-fledged LED hub.
Perhaps the biggest head-scratcher is dealing with the Reset LED SW wire. You’ll notice it already plugged into the fan hub in the top left behind the motherboard for obvious reasons: it connects to the four ARGB fans to cycle through plenty of lighting presets, keeping them in unison. Unfortunately, the wire comes part and parcel with the cluster of power cables that need to reach the other end of the system with no slack. You can peel it away carefully, but it’s not the most user friendly, especially for beginners who wouldn’t dream of prying wires apart.
Fortunately, the end result is addressable RGB, controllable via motherboard software or the case’s top-mounted button. You’ll spot a tasteful glow, amplified by the white case’s reflective nature. Beauty is in the eye of the beholder and the black chassis is still a looker even with lighting shining, but this feels like further proof that everything’s better in white – at least if you want to make a statement.
Conclusion
Endorfy Arx 700 ARGB is not trying to reinvent the wheel. Instead, it adds more spokes and paints it in two colours. This is a chassis that understands its audience: PC builders who want good airflow, visual flair, and a roomy internal layout without paying premium brand prices.
At just over £100, it’s one of the few cases that ships with four large, reliable 140mm ARGB fans, supports a decent range of water-cooling configurations, and doesn’t fall apart the moment you look at it sideways. It handles modern GPUs with ease, and leaves enough cable management space to keep builds looking sharp, even if it requires a little more patience.
Of course, it’s not without flaws at this price range. Reattaching the side panel is a touch clunky, and the rear cable space gets tight once you factor in fan wiring. But these are quirks that require some thought and a dash of builder’s confidence, not dealbreakers. When compared to airflow contemporaries in its own price bracket, like be quiet! Pure Base 501 DX, Arx 700 ARGB holds its own. If you’re after a high-airflow case that looks great in white, plays nicely with RGB, and gives you plenty of building flexibility, Arx 700 ARGB is hard to ignore.
