24 Cores. 1.92 Liters. The Numbers Don't Add Up, Until You Use It.
When your "compact" PC has more cores than most workstations, you're not saving desk space, you're gaining an unfair advantage.
Why This Machine?
Most compact PCs cut corners. The DeskMini B860 cuts size instead, and then keeps going.
Packing an Intel Core Ultra 9 285 (24 cores, up to 5.7 GHz) into a 1.92-liter chassis smaller than most textbooks, this system doesn't just save desk space, it redefines what small-form-factor can do. Dual M.2 slots (one Gen5, one Gen4), 2.5G Ethernet, Thunderbolt 4, and quad display output mean it handles multi-monitor productivity, AI-assisted tasks, and professional workloads without breaking a sweat. Noctua cooling keeps it near-silent. Energy Star 9.0 certified for efficiency.
1.92 liters. 24 cores. Built-in AI. Near-silent.
