COOLER MASTER Elite 681 ARGB ATX Mid Tower Cabinet ( Black )

The Cooler Master Elite 681 ARGB is an ATX mid tower cabinet designed for enthusiast builds that demand both thermal headroom and visual impact. Its most distinctive design element is the 270° full-view tempered glass enclosure, formed by dual tempered glass panels with 45° bevel edges that create a near-seamless join — giving your components an unobstructed showcase from front and side simultaneously. The Elite 681 uses a true dual-chamber architecture that physically separates the motherboard compartment from the power supply and cable management zone. The PSU is mounted at the top of the right chamber, and 95mm of cable management depth is provided to keep routing tidy without compromise. This separation also channels airflow more predictably through the main chamber. Cooling capability is a central design priority. The case ships with four pre-installed ARGB PWM fans: three 120mm reverse-blade fans mounted on the side intake panel and one 120mm ARGB PWM fan at the rear exhaust. All four use daisy-chain connectors and are compatible with major motherboard ARGB software for unified lighting control. For builders who need more, the Elite 681 supports up to ten fans total and accommodates radiators up to 360mm at the top, 360mm at the bottom, and 280mm at the side mount — enabling full custom loop or high-end AIO configurations. The front I/O panel includes two USB 3.0 Type-A ports and one USB 3.2 Gen 2×2 Type-C port running at up to 20Gbps, along with a 3.5mm combo audio jack. Drive storage covers up to two 3.5-inch HDDs and up to three 2.5-inch SSDs. Seven expansion slots, 160mm CPU cooler clearance, 410mm GPU clearance, and support for ATX motherboards (plus Micro-ATX and ITX) round out the compatibility profile. Large mesh ventilation zones on the top and bottom panels further support passive and active airflow.
