Build Integration

The mid-tower case measures 477mm deep by 220mm wide by 486mm high and includes a 240mm liquid cooler for the CPU. A Thermaltake 850W 80 PLUS Bronze power supply provides power, while the PRIME X870-P motherboard offers rear I/O with two USB4 ports at 40Gbps, one USB 10Gbps port, three USB 5Gbps ports and four USB 2.0 ports. Internal expansion includes four M.2 connectors and two SATA 6Gb/s ports, with drive bays for three 3.5-inch and three 2.5-inch devices.

Sustained Operation

Under continuous load the 240mm liquid cooler and case airflow — three 120mm front fans, one 120mm PSU-shroud fan and one 120mm rear fan — manage CPU thermals. The 128MB L3 cache and 192GB DDR5 configuration support prolonged compute workloads without memory pressure. The Samsung 990 PRO SSD delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for sustained data throughput. Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 with Bluetooth 5.4 maintain network connectivity during extended sessions.
