Adamant Custom
Liquid-cooled 24-core desktop with 128GB DDR5, 4TB NVMe and RTX 5070 graphics for gaming and creative workloads
This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with a 360 mm liquid cooler and 128 GB of DDR5 memory. The GeForce RTX 5070 with 12 GB of video memory handles rendering and modern game engines. A 4 TB Samsung 990 PRO NVMe drive provides primary storage. Windows 11 Pro is installed and the system is described as AI Ready.
The black mid-tower chassis uses tempered glass side panels and includes two 140 mm PWM front fans. Front-panel I/O offers one USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and audio jacks. The rear I/O adds a USB4 Type-C port, multiple USB 3.2 and 2.0 ports, 2.5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. Internal bays provide two 3.5-inch and two 2.5-inch slots alongside four M.2 connectors on the Gigabyte Z890 Eagle motherboard.
Builders moving from an air-cooled platform with 64 GB of memory gain quieter thermal headroom and double the RAM capacity for large timelines or virtual machines. The jump is worthwhile when single-thread speeds up to 5.70 GHz and the 36 MB L3 cache reduce compile times. Buyers who need more than 4 TB of high-speed storage or a second graphics card should plan around the available M.2 slots and power budget.

The front-panel Type-C port runs on USB 3.2 Gen 2x2, giving a maximum throughput of 20 Gbps.
The mid-tower case measures 447 × 215 × 469 mm and the 360 mm radiator mounts to the three 140 mm fan positions at the front.
The all-in-one cooler arrives pre-filled; the critical step is peeling the protective film off the cold-plate before securing it to the LGA 1851 socket.
