A liquid-cooled mid-tower desktop with a 24-core Intel Core i9-14900K, 64GB DDR5, 4TB NVMe SSD and GeForce RTX 5060 Ti graphics
This system pairs a 24-core Intel Core i9-14900K with a 360 mm liquid cooler and 64 GB of DDR5 memory. The GeForce RTX 5060 Ti 8 GB GPU handles modern titles at high settings. A 4 TB Samsung 990 PRO NVMe drive provides fast storage for games and applications. It ships with Windows 11 Pro pre-installed in a Corsair 4000D mid-tower case.
Moving from an air-cooled platform to this 360 mm liquid loop keeps the 24-core processor near its 6.00 GHz boost clocks during sustained workloads. The Z790 PRIME motherboard supports up to 192 GB of DDR5 across four slots for future expansion. The jump is worth it when rendering, compiling or streaming pushes an air cooler past its thermal limits.
The Corsair 4000D chassis offers standard ATX layout with front-panel USB 3.2 Type-C and audio combo jack. Internal bays include two 3.5-inch and two 2.5-inch positions for extra drives. The Thermaltake Smart 850 W 80 PLUS Bronze PSU uses a single 140 mm fan and Japanese main capacitors. First-boot issues usually stem from loose DDR5 modules or an unseated GPU power cable.

The 360 mm AIO is pre-installed in the Corsair 4000D mid-tower, which measures 490 x 239 x 486 mm and supports a 360 mm radiator up front.
The 360 mm AIO arrives filled and sealed; the only install step is screwing the radiator fans to the front panel and plugging the pump header into the Z790 motherboard CPU_FAN connector.
The sealed 360 mm Quiet Edition loop is maintenance-free for the usable life of the i9-14900K; no coolant change is required unless a leak develops.
