Liquid-cooled tower with 24-core Intel Core Ultra 9 285K, 32GB DDR5, 1TB NVMe and RTX 5070 graphics
This system pairs a 24-core Intel Core Ultra 9 285K with 32GB DDR5 and an Nvidia GeForce RTX 5070 12GB. A 1TB Samsung 990 PRO NVMe drive provides fast storage for large project files and game libraries. It targets professionals who need CPU multi-thread throughput alongside modern GPU acceleration.
The 360mm liquid cooler keeps the 24-core processor stable during long renders or compile jobs without the throttling seen on smaller air coolers. The RTX 5070 12GB frame buffer handles high-resolution textures and compute workloads without spilling to system memory. An 850W 80 PLUS Bronze PSU delivers continuous power to both components under full utilisation.
Front and rear 140mm case fans run at 1500rpm with a rated 30dBA, moving air through the Ceres 300 chassis while the AIO radiator exhausts CPU heat. The Thermaltake Smart 850W unit uses a Japanese main capacitor and a quiet 140mm fan for low-noise power delivery. Windows 11 Pro manages modern sleep states to reduce idle draw.

The two front and one rear 140 mm fans each spin at 1500 rpm and are rated at 30 dBA, so the chassis stays quiet even under sustained load.
The RTX 5070 12 GB uses standard DisplayPort and HDMI outputs; have the matching cables ready for your monitor.
Yes, the motherboard provides four SATA 6 Gb/s ports and the case includes a bay that accepts one 3.5-inch or two 2.5-inch drives.
