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.
