Ready-to-game desktop

This Adamant Custom desktop arrives assembled with Windows 11 Pro installed and a 20-core Intel Core Ultra 7 265K processor. Liquid cooling handles the CPU while a GeForce RTX 5090 with 32GB memory drives the graphics. The system targets gamers and media creators who want high performance without building it themselves.

Straightforward component access

The Ceres 300 mid-tower case uses tempered glass panels that remove with thumbscrews, giving clear access to the motherboard and drive bays. Four M.2 slots are populated by two 4TB Samsung 990 PRO SSDs, leaving two slots open for expansion. The 240mm AIO cooler is pre-filled and mounted, so no coolant handling is required. Front-panel connectors include USB 3.2 Gen 2 Type-C, two USB 3.0 ports and HD audio.

Suits single-GPU high-refresh builds

This configuration suits buyers who need one powerful GPU, 32GB DDR5 and 8TB of fast NVMe storage in a compact chassis. It does not suit builders who need a second graphics card, additional 3.5-inch drive bays beyond the single convertible bay, or a larger radiator than the 240mm unit provided.

Questions about this item

How do I verify the RTX 5090 32GB GPU and Intel Core Ultra 7 265K CPU are performing correctly after first boot?

Open Task Manager to confirm the GPU shows 32GB dedicated memory and the CPU lists 20 cores at 3.7GHz base clock. Run a benchmark such as 3DMark to validate the RTX 5090 scores and Cinebench to check the Core Ultra 7 265K reaches up to 5.50GHz boost.

Which components ship inside the Ceres 300 case and what must I supply myself?

The system arrives fully assembled with the Z890 TUF motherboard, 20-core Core Ultra 7 265K, 240mm liquid cooler, 32GB DDR5, two 4TB Samsung 990 PRO SSDs, RTX 5090 32GB, 1000W 80 PLUS Gold PSU, Windows 11 Pro, Wi-Fi 7 and Bluetooth5.4. Only a monitor, keyboard and mouse are needed separately.

Should I choose the 32GB DDR5 configuration or plan to expand toward the 192GB maximum?

The board provides four DDR5 slots with 32GB installed. For pure gaming 32GB is sufficient; content creators running heavy multitasking or VMs can add matching DDR5 modules later to reach the 192GB ceiling without replacing the existing kit.
