Multi-GPU Barebones Mining Rig

I’m ready to purchase a barebones mining system that can accept full-length graphics cards directly into the motherboard—no riser-style power headers. I need a board (or complete chassis) that offers 8 – 10 true PCI-e x16 mechanical slots so each GPU seats just as it would in a standard desktop.

Essential components I expect in the package:
• Reliable motherboard with those 8-10 PCI-e x16 slots
• Matching power supply capable of driving all slots under load
• On-board or included VGA and HDMI outputs
• CPU already installed and Windows 11 loaded on an internal drive
• Front-panel USB, integrated Wi-Fi, and all basic I/O
• Basic peripherals: mouse and keyboard

Brand isn’t critical—as long as the hardware is dependable and parts are readily replaceable (Asus, MSI, Gigabyte, or an industrial maker all acceptable).

What I need from you:
1. A clear parts list and photos or spec sheets proving the board really has 8–10 x16 mechanical slots.
2. Total price, lead time, and shipping options to my location.
3. Confirmation that Windows 11 will boot out of the box and all drivers are pre-installed.

If you’ve supplied or built rigs like this before, share the model numbers or a quick rundown of previous builds so I can verify reliability. Once we agree, I’ll fund the project and we can sort out milestones for procurement, assembly verification, and final delivery.
