12-Core Liquid Cooled Workstation
This business desktop pairs a 12-core AMD Ryzen 9 9900X processor with a 240mm liquid cooler for sustained performance. It ships with 32GB of DDR5 memory and an Nvidia RTX A400 graphics card driving four Mini DisplayPort outputs. The system targets content creators who need reliable multi-threaded throughput in a compact tower.
8TB NVMe plus 10TB HDD storage
Two 4TB Samsung 990 PRO SSDs combine for 8TB of PCIe 4.0 NVMe capacity with sequential reads up to 7450 MB/sec. A 10TB hard drive with 256MB cache adds deep archival space. This dual-tier layout lets active projects stay on fast flash while large media libraries remain on spinning media.
X870 motherboard with USB4 and Wi-Fi 7
The TUF X870-PLUS board supplies two USB4 Type-C ports at 40Gbps alongside multiple 10Gbps and 5Gbps USB connections. Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 provide wired and wireless networking. Four M.2 slots and two 3.5-inch bays remain open for future expansion inside the Antec P20 case.
