A liquid-cooled gaming desktop with a 24-core Intel Core i9-14900K, 64GB DDR5, 4TB NVMe SSD and GeForce RTX 5070 12GB graphics
This mid-tower desktop pairs a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5070 graphics card and 64GB of DDR5 memory. A 360mm liquid cooler manages CPU thermals while a 4TB Samsung 990 PRO NVMe drive supplies primary storage. The system ships with Windows 11 Pro installed and includes Wi-Fi 6 and BLUETOOTH 5.2 connectivity.
The Z790 TUF motherboard provides four M.2 slots and four SATA ports, so the single 4TB NVMe drive leaves room for additional solid-state or hard-disk storage. The Thermaltake Smart 850W 80 PLUS Bronze power supply delivers enough headroom for the installed components and includes over-voltage, under-voltage, over-power and short-circuit protection. Front-panel I/O offers two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port and audio jacks for quick peripheral access.
The PCIe 4.0 x4 link feeding the 4TB SSD caps sequential reads at 7450 MB/s and writes at 6900 MB/s, so workloads needing higher sustained throughput will require a PCIe 5.0 platform. The RTX 5070 carries 12GB of video memory, which limits texture pools and frame buffers at very high resolutions. Memory expansion tops out at 192GB across four slots, and the 2.5Gb Ethernet port sets the wired network ceiling.

The 360mm Quiet Edition AIO is a sealed unit designed to run for the life of the CPU without any fluid changes or refills.
The Thermaltake Smart 850W 80 PLUS Bronze PSU will reach its 850 watt ceiling before the 24-core i9-14900K or RTX 5070 hit their thermal limits under sustained full load.
The 360mm Quiet Edition AIO and 140mm PSU fan keep the i9-14900K cool with low noise, while three 120mm front case fans move air through the Antec P20 mid-tower.
