Out of the box, the Endorfy Arx 700 Air doesn't push the design envelope in terms of uniqueness, but the build feels study with the classic material mix of steel, plastic and mesh.
Worth noting is the fact that the entire front is made of a fine mesh sheet, so that there is no need for another layer of air obstructing dust filtration. In the rear, you can see, that the Arx 700 Air provides a traditional layout, but thanks to its wide body, there will be tons of room for air cooling and large GPUs. If you look closely, you will also notice hooks for zip ties on the left edge, which means you should easily be able to cable manage your external wiring. This is a nice touch we have seen a few times before, but Endorfy could really drive this home by including some additional Velcro cable ties to use for this purpose.
The main side panel of the Arx 700 Air is made of clear, nicely framed glass that is held in place by two thumb screws in the back of the chassis. Turning it around, you will find a solid steel panel to cover any cable management. Looking closely at the front panel, it sports fine mesh metal strips as an additional air intake.
You may simply pop the front mesh cover off to get access to the three pre-installed 140 mm fans, however if you remove the whole cover assembly, you may also access the removable mounting plate these cooling units sit on. This is really useful when installing liquid cooling setups in this part of the chassis. At the top edge, there appears to be something very similar to braille, but after checking in with Endorfy on this, these dots are just meant to make grabbing unto the front mesh panel easier.
In the rear, the bottom sports a removable PSU mounting frame which is held in place by four thumb screws. Above that are the seven classic expansion slots, each protected by a fine mesh, reusable cover. Endorfy also placed a solid, swing open filler piece here for good measure. At the top, you will find yet another 140 mm fan, set to push hot air out the back of the enclosure.
In the top, there is a metal cover with fine mesh to match that of the front, once again eliminating the need for an additional dust filtration layer. Below it, there is yet another 140 mm fan, specifically set up to pull hot air out right above the CPU socket. You may fit three 120 or 140 mm fans here and Endorfy also mentions radiator compatibility of up to 360 mm in this area of the chassis. As the mounting holes are away from the motherboard as far as possible, you should have no issue with interference either, which is nice to see! Next to this area, there is the I/O panel, which consists of USB-C, two USB-A, audio ports and the usual power and reset button LEDs.
On the underside of the Endorfy Arx 700 Air, there is yet another fine metal mesh dust filter. While this one uses magnetic strips to hold in place, you may pull it out from the front of the chassis fairly easily, so that you won't have to tip over a running system to get to it for cleaning purposes.
