Built for high-end gaming and multitasking

This desktop pairs an Intel Core i9-12900K processor with an RTX 4060 8GB graphics card, delivering strong frame rates in modern titles and responsive performance for creative workloads. It ships with Windows 11 Pro pre-installed and activated, plus a 1TB NVMe drive for fast game and application loading. The system is aimed at enthusiasts who want a powerful foundation without paying for memory they may already own.

Memory must be DDR5 modules you supply

The B660M motherboard supports DDR5 only and the unit ships with zero RAM installed, so you must provide compatible sticks before the PC will post. No other memory generation will fit the slots, and the board cannot run without modules populated. This BYOR approach lets you choose capacity and speed to match your budget or reuse existing DDR5 kits.

Straightforward assembly with thumbscrew access

The Zalman T3 Plus case opens via four thumb screws on a frameless tempered glass panel, giving clear access to the motherboard slots for RAM installation. Three pre-installed 120mm chassis fans and an included CPU cooler handle airflow out of the box. Front I/O provides two USB 2.0, one USB 3.0 and 3.5mm audio jacks, while the rear offers six USB ports.

Questions about this item

How does the i9-12900K perform inside this chassis with air cooling?

The 650W supply and three 120mm case fans keep the i9-12900K fed and ventilated, while the included Cooler Master-class CPU cooler handles its thermal load during gaming and multitasking.

What does the B660M chipset limit on this board?

The B660M chipset locks CPU multiplier control, so the i9-12900K runs at stock boost clocks, and it caps the primary M.2 slot to PCIe 4.0 x4 speeds for the 1TB NVMe drive.

Will a standard DDR5 DIMM kit fit the four slots on this B660M board?

Yes, the motherboard uses the DDR5 form factor with four long DIMM slots; any standard desktop DDR5 kit installs without clearance issues from the air cooler or the 355mm deep case.
