Liquid-cooled tower with a 24-core i9-14900K, RTX 5070 Ti graphics, 32 GB DDR5 memory and a 1 TB NVMe SSD
This desktop pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5070 Ti 16GB GPU, 32GB DDR5 memory and a 1TB Samsung 990 PRO NVMe SSD. It targets creators and enthusiasts who need high single-thread speed and modern ray-tracing hardware in a ready-to-run Windows 11 Pro tower. Buyers who want more storage bays or a second graphics card should look elsewhere.
A 360mm quiet-edition liquid cooler handles the CPU while front 200mm ARGB fans, a rear 120mm ARGB fan and a dedicated 120mm GPU fan move air through the CoolerMaster HAF 500 case. The Thermaltake Smart 850W 80 PLUS Bronze unit supplies power with a 140mm low-noise fan and Japanese main capacitors. Protections include over-voltage, under-voltage, over-power and short-circuit safeguards.
The Gigabyte Z790 AORUS motherboard provides four DDR5 slots supporting up to 192GB, four M.2 connectors and six SATA 6Gb/s ports with RAID 0, 1, 5, 10. Rear I/O includes USB 3.2 Gen 2 Type-C, multiple USB 3.2 Gen 1 and 2.0 ports, 2.5Gb Ethernet, Wi-Fi 6 and Bluetooth 5.2. All configurations are customisable at order time.

Mount the cooler using the LGA 1700 bracket included with the motherboard, then connect the pump header and fan headers; the step people miss is removing the protective film from the cold-plate before seating it.
The closed-loop AIO requires no coolant refill; plan to replace the 140mm radiator fans and the PSU 140mm fan when bearing noise appears, typically after several years of continuous use.
The CPU will hit its 6.00 GHz thermal ceiling first, causing the 360mm liquid cooler to ramp fans to maximum speed while the processor throttles to stay within its temperature target.
