Liquid-cooled 24-core Intel Core Ultra 9 desktop with 32GB DDR5, 2TB NVMe, 10TB HDD and RTX 5070 Ti graphics
This desktop combines a 24-core Intel Core Ultra 9 285K processor with 32GB of DDR5 memory and a GeForce RTX 5070 Ti graphics card. A 360 mm liquid cooler handles the CPU thermal load while the system ships with Windows 11 Pro installed. It targets creators and gamers who need high multi-threaded throughput and modern GPU features in a single pre-built chassis.
The 2 TB Samsung 990 PRO operates at PCIe 4.0 x4 speeds, capping sequential reads near 7450 MB/s and writes near 6900 MB/s. The motherboard provides three M.2 slots and four SATA 6 Gb/s ports with RAID 0, 1, 5, 10 support, but no PCIe 5.0 M.2 interface is present. Wired networking tops out at 2.5 GbE while wireless uses Wi-Fi 7 2x2 and Bluetooth 5.4.
The 360 mm quiet-edition AIO uses a 140 mm radiator fan and mounts inside a tempered-glass chassis measuring 447 x 215 x 469 mm. Front-panel I/O includes one USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and dual audio jacks. Rear I/O adds USB4 Type-C, USB 3.2 Gen 2, four USB 3.2 Gen 1 and four USB 2.0 ports. Internal bays hold two 3.5-inch and two 2.5-inch drives. An 850 W 80 Plus Bronze PSU with Japanese main capacitors powers the build.

The 2TB Samsung 990 PRO NVMe gives up to 7450 MB/s reads for OS and active projects, while the 10TB HDD adds bulk capacity for media libraries; a single larger NVMe would cost more per terabyte and reduce total space.
The Intel Core Ultra 9 285K can reach 5.70 GHz on light-threaded tasks such as game logic or compile bursts, while the 360 mm liquid cooler keeps sustained all-core speeds high during long renders.
The M.2 slot runs PCIe 4.0 x4, so the 990 PRO hits its rated 7450 MB/s sequential read ceiling; a PCIe 5.0 drive would not run faster on this motherboard.
