System overview

This GRI gaming desktop ships as a complete tower with an Intel Core i9-12900K processor and a GeForce RTX 5070 12GB graphics card already installed. Windows 11 Pro is pre-activated and updated. The only missing part is system memory, which you supply yourself.

Memory flexibility

The motherboard uses DDR4 slots and the system is sold without RAM so you can reuse sticks you already own or choose new modules that match your budget and speed preference. This approach avoids paying for memory you may not need.

Build checklist

Verify that your DDR4 modules are compatible with a B660M chipset and that the total capacity you plan to install fits the board's slot count. Confirm the 650W power supply covers the CPU and GPU combination you are running, and check that the 355 x 206 x 422 mm case fits your workspace.

Questions about this item

Will the Zalman T3 Plus case with its 355 mm depth and 120 mm fans fit my desk space?

The case measures 422 mm high, 206 mm wide and 355 mm deep. Three 120 mm chassis fans are pre-installed behind the tempered-glass side panel, which is secured by four thumb screws for easy removal.

How do I install my own DDR4 memory on the B660M motherboard, and what mistake should I avoid?

Open the side panel, locate the four DDR4 slots on the B660M board, align each module notch with the slot key and press firmly until the retention clips click; the common error is seating modules incompletely so the system fails to POST.

What future maintenance or replacement should I plan for the 650 W power supply and air cooler?

Dust the CPU cooler fins and three 120 mm case fans every few months to maintain airflow; the 650 W unit has headroom for the i9-12900K and RTX 5070, but replace it if you later add power-hungry components or hear coil whine.
