Liquid-cooled tower with a 24-core Intel Core i9-14900K, 32GB DDR5, 1TB NVMe SSD and an RTX 5070 GPU for 4K gaming and heavy creative workloads
This liquid-cooled tower pairs a 24-core Intel Core i9-14900K with 32 GB of DDR5 memory and a GeForce RTX 5070. It ships with Windows 11 Pro and a 1 TB NVMe drive, targeting creators and engineers who need high single-thread speed plus GPU acceleration out of the box.
The i9-14900K reaches 6.00 GHz boost with 36 MB L3 cache on the LGA 1700 platform. Buyers whose software scales beyond 24 cores or demands ECC memory will need a different platform, as this board tops out at 192 GB non-ECC DDR5 across four slots.
The Samsung 990 PRO delivers up to 7450 MB/s reads and 6900 MB/s writes, while the RTX 5070 provides 12 GB of video memory. Projects exceeding 1 TB of active assets or 12 GB VRAM per scene will require additional storage or a higher-tier GPU.
Measured against everything we stock in Gaming PCs, at today’s prices. Recalculated every night.

The 360 mm AIO keeps the 24-core processor near its 3.2 GHz base while allowing bursts up to 6.00 GHz across its 32 threads, so heavy renders or compiles sustain high throughput without thermal throttling.
The four-lane Gen 4 connection lets the 1 TB drive hit its rated 7450 MB/s reads and 6900 MB/s writes, so game loads, project opens and file copies run at the drive's full speed rather than a bus bottleneck.
Yes — the 4000D supports radiators up to 360 mm at the front and graphics cards up to 450 mm, so the supplied AIO and the RTX 5070 install without clearance issues.
