OnLogic ML510: The Gold Standard in Industrial Computing

Industrial Power. Fanless Silence. Unbeatable Reliability.

If you’ve been waiting for the right time to upgrade to OnLogic’s legendary "Small Orange Computers," this is it. Engineered for 24/7 operation in environments that kill standard PCs, the ML510 is a silent powerhouse built like a tank.

Why the ML510 is a "Set It and Forget It" Solution:

  • 100% Fanless & Ventless: With no moving parts and a solid-state design, dust, grease, and debris stay out. It’s the ultimate solution for machine shops, warehouses, and dusty environments.

  • Industrial Grade Durability: A rugged metal chassis protects your data from vibration and heat.

  • Zero Noise: Passive cooling makes this PC completely silent—perfect for recording studios, medical offices, or home media servers.

  • Pro-Level Connectivity: Unlike basic desktops, this unit is packed with legacy and modern ports to connect to almost anything (see below).

The Port Layout (Maximum Connectivity):

  • Dual Display: 2x DisplayPorts (Run dual 4K monitors with ease)

  • Dual LAN: 2x GbE Ethernet ports (Ideal for network redundancy or IoT gateways)

  • Legacy Support: 2x Serial Ports (RS-232) for connecting to CNC machines, sensors, or older hardware.

  • High-Speed Data: Multiple USB 3.2 ports for fast peripherals.

Perfect For:

  • Industrial: Warehouse management, shop-floor controllers, CNC integration.

  • Commercial: Medical offices, firehouses, schools, and digital signage.

  • Home: The ultimate silent Media Server (Plex/Home Assistant) or reliable home office hub.

Optional Add-On: We have compatible wall mounts available! Perfect for mounting your PC under a desk, behind a monitor, or directly to a wall to save space.

Cosmetic Notes: These computers may have cosmetic blemishes on the body from usage but nothing major. It does not affect the functionality of the PC.
