The Arx 500 Air brings a wide smile to your faces. No wonder, as Endorfy has packed all its knowledge into this case. Spoiler alert - it has turned out like a dream. This is one of the largest cases Endorfy has ever developed, just a bit shorter than the Arx 700 series. It measures 486 x 228 x 429 mm - enough to accommodate a large cooling system (up to 179 mm), 7 fans (including 5 Stratus 140 PWM fans that Endorfy provides for a good start), and plenty of graphics cards. Everything sits in a pleasant breeze, as the finely perforated front and top panels allow fresh air in while keeping dust out. You can check it through the tempered glass window.
