Built for media work and high-refresh gaming

This desktop pairs a twelve-core Ryzen 9 9900X3D with 128GB of DDR5 and a 2TB NVMe drive. The RTX 5070 handles 1440p and 4K workloads while the liquid cooler keeps the CPU stable under sustained loads. Windows 11 Pro is installed and ready for professional pipelines.

Replaces a workstation that bottlenecks on memory

The jump is worth it when 64GB of RAM is no longer enough for timeline scrubbing, virtual machines or large texture sets. The Samsung 990 PRO delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s over PCIe 4.0x4. Builders who need a second GPU or more than 192GB of memory should look elsewhere.

PCIe 4.0x4 caps the primary SSD at 7450 MB/s

The X870 motherboard provides four M.2 slots but the fastest lane topology is limited to the 4.0 standard. USB4 ports reach 40Gbps while rear USB 10Gbps and 5Gbps ports cover peripherals. Wi-Fi 7 and 2.5Gb Ethernet handle network traffic without extra cards.

Questions about this item

What clearance is needed for the 240 mm AIO liquid cooler?

The 240 mm AIO fits in the Design North case measuring 447 x 215 x 469 mm with front 140 mm fans; verify radiator clearance against the front panel before mounting.

How is the CPU cooler mounted on the AM5 socket, and what step is often missed?

Attach the supplied AM5 brackets to the pump block, apply thermal paste, then secure the pump to the motherboard back-plate; the step often missed is removing the protective film from the cold-plate before installation.

Which drive slots remain free for future storage upgrades?

The X870-PLUS board provides four M.2 connectors — one used by the 2 TB Samsung 990 PRO — and the case has two 3.5 inch plus two 2.5 inch internal bays, all with SATA 6 Gb/s headers available.
