Liquid-cooled tower with 24-core Intel Core Ultra 9 285K, 32GB DDR5, 1TB NVMe plus 10TB HDD and RTX 5060 graphics
This system is built around a 24-core Intel Core Ultra 9 285K processor running at 3.7 GHz with a peak of 5.70 GHz. A 360 mm liquid cooler keeps the CPU temperatures under control during heavy workloads. The Z890 motherboard provides a stable platform for the high core count.
The combination of 32 GB DDR5 memory, 1 TB NVMe SSD and 10 TB hard drive suits creators who need fast scratch space and large local archives. Windows 11 Pro and integrated 7.1 audio support professional software environments. Buyers who want more than 32 GB of memory out of the box should look at a different configuration.
The GeForce RTX 5060 with 8 GB of video memory defines the 1440p gaming performance level of this PC. It handles modern titles at high settings but is not intended for 4K ultra gameplay. Choose a system with a higher-tier GPU if 4K frame rates are the priority.

Yes, the CPU fits the LGA 1851 socket on the included Gigabyte Z890 UD board; the system ships fully assembled so no separate motherboard purchase is needed.
The case provides two internal 3.5-inch bays and two 2.5-inch bays, and the motherboard offers four SATA 6Gb/s ports with RAID 0, 1, 5, 10 support for legacy drives.
Monitor core temperatures and clock speeds in Windows Task Manager or a hardware utility; sustained speeds at or above 3.7 GHz with temperatures well below the thermal limit confirm the cooler is working as intended.
