I have both built and unbuilt active hubs.
1. (Qty 2) Unbuilt 16 Port Active Hub: $15 + shipping
2. (Qty 1) Unbuilt 16 Port Passive Hub: $10 + shipping
3. (Qty 2) Built Active Hubs: $25 ea + shipping (will have corrosion X spray on them). Will remove from the battery box for easier shipping, and add 750W power supply
I can send pics, if wanted.
