Built for High-End Workloads

This liquid-cooled desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 and 32GB of DDR5 memory. It targets professionals and enthusiasts who need sustained compute and graphics performance for rendering, simulation or 4K gaming without building a custom loop themselves. The Z790 motherboard and 1200W Gold-rated supply give the platform headroom for heavy all-core loads. Windows 11 Pro is installed and ready to use.

Fits a Mid-Tower Build

The Corsair 4000D chassis measures 490 x 239 x 486 mm and includes a 360 mm AIO cooler mounted to the CPU. Two 3.5-inch and two 2.5-inch internal bays remain free for extra drives, while three M.2 slots on the board accept further NVMe storage. Front I/O supplies one USB 3.2 Type-C and two USB 3.2 Gen 1 ports plus audio; the rear adds 2.5Gb Ethernet, Wi-Fi 6 and Bluetooth 5.2. No optical drive is fitted, leaving the 5.25-inch bay empty.

Replaces Older Workstations

Builders moving from a system limited to 64GB memory or a single GPU will gain the 192GB DDR5 ceiling and the RTX 5090's 32GB frame buffer. The 4TB Samsung 990 PRO delivers 7450 MB/s reads and 6900 MB/s writes, while the 10TB hard drive adds bulk capacity. If your current platform lacks PCIe 4.0 M.2 support or 2.5Gb LAN, this unit closes those gaps. Buyers who need more than two additional 3.5-inch drives or a larger radiator than 360 mm should consider a full-tower alternative.

Questions about this item

Will the 360 mm AIO liquid cooler keep the 24-core i9-14900K from throttling during long rendering sessions?

The 360 mm Quiet Edition AIO is sized for the 24-core i9-14900K and its 3.2 GHz base clock, providing continuous liquid cooling under sustained multi-thread loads.

How loud is the system when the RTX 5090 and CPU run at full load for hours?

The 360 mm AIO uses a low-noise 140 mm fan and the Thermaltake 1200W Gold PSU has an ultra-quiet 140 mm fan, so acoustic output stays low even during extended all-day workloads.

Does the motherboard include Wi-Fi 6 and Bluetooth 5.2 so I don't need extra adapters?

Yes, the Z790 PRIME motherboard integrates Wi-Fi 6 (802.11ax) and Bluetooth 5.2, plus Intel 2.5 Gb Ethernet, so no separate wireless cards are required.
