Unique All-in-One AI-optimized PC Build

Custom All-in-One PC Build (Laptop Board Inside a 120Hz Monitor) — Local AI Image Recognition
Summary
I'm looking for an experienced hardware builder to design, build, test, and ship a custom all-in-one PC: a laptop motherboard (with dedicated GPU) mounted inside a repurposed desktop monitor, powered by a single cable. The concept is based on this video: https://youtu.be/7FStfdGjAwc — but with a closed, gaming-style enclosure and a proper integrated power button.
Primary use: running AI image-recognition models locally. I'll handle all AI software myself — this job is hardware only: choosing the parts, building the unit, and delivering it with Windows installed and drivers working. The main thing this affects for you is component choice: an NVIDIA dGPU with CUDA support and as much VRAM as the budget allows is the priority.
Secondary goal: noticeably cheaper than an equivalent desktop PC while staying close in performance.
Deliverable
One fully assembled, tested, working unit shipped to me, plus a parts list, wiring diagram, photos of the internals before closing the case, and a short setup/maintenance guide.
Core components
Laptop motherboard with NVIDIA dGPU (RTX 30/40-series or newer preferred), sourced from a donor laptop with a broken screen/chassis to save cost. Include the CPU, RAM (32 GB preferred), NVMe SSD (1 TB preferred), Wi‑Fi/BT card, and the laptop's original cooling (heatsink + fans).
Monitor: 24–27", 1080p or 1440p, 120 Hz minimum (4K not required). Ideally a model with a thin, flat back and room to mount hardware. Its original driver board and power supply will be reused.
Powered USB hub, monitor driver/controller board, and voltage regulator(s) so the entire unit runs from one wall cable (single power brick or internal PSU — your call, but justify it in the proposal).
Extra internal case fan for the closed enclosure. Size the power supply with headroom for the laptop board at full GPU load + monitor + hub + fan (please show the power budget in your proposal).
Enclosure & appearance
Closed sides — no exposed internals. Ventilation only through purposeful vents/mesh on the sides and rear.
Gaming aesthetic (angular lines, mesh vents, optional subtle RGB accent). Tidy, finished look — not a prototype.
Interior must be fully enclosed and dust-managed as far as practical.
Power button
A proper monitor-style tactile button (no improvised paper/copper switch) built into the bezel or underside.
One press powers on both the laptop board and the monitor; a second press / OS shutdown powers off both. Wire this via the laptop board's power-switch header and the monitor driver board's power line (relay, MOSFET, or small microcontroller — your choice, please explain).
Rear/bottom I/O (must be reachable from the underside of the monitor)
1× DisplayPort out
1× HDMI out
1× 3.5 mm audio (aux) jack
1× USB‑C
1× 5 GbE Ethernet (if the board has no 5GbE, use a quality USB‑C/Thunderbolt 5GbE adapter mounted internally)
Plus a few USB‑A ports from the hub for keyboard/mouse
Port rules:
If the chosen laptop board already has these ports on one edge, the board may be oriented so that edge faces the underside — as long as the interior stays fully enclosed.
If the ports are on different edges, use internal extension cables/adapters and mount panel‑style ports flush on the bottom edge.
All external ports must be labeled.
Software / configuration (basic setup only — no AI software work needed)
Windows 11 (Pro preferred). If the donor laptop has an embedded OEM Windows key, reuse it; otherwise include a legitimate license in the BOM.
BIOS/OS configured so the unit boots and displays on the internal panel with no lid/laptop-screen issues.
Current NVIDIA driver installed and the GPU confirmed working (a screenshot of GPU‑Z or a quick 3D benchmark is enough). I'll install everything else myself.
What I need in your proposal
Proposed laptop board/donor model and monitor model, with prices and where you'd source them.
Full BOM with estimated total cost, split into parts and labor.
Power budget calculation and PSU choice.
Enclosure approach (3D‑printed, sheet metal, modified monitor shell, etc.) and a rough sketch/render.
Power‑button circuit description.
Timeline, warranty on workmanship, and insured shipping method/cost to Kansas, USA.
Examples of similar builds you've done.
Budget: $1,200–$1,600 all‑in (parts, labor, Windows license, insured shipping). Bids up to ~$1,800 considered if the extra cost buys a meaningfully better GPU (more VRAM).
Location: Kansas, USA — 120 V mains. US‑based builders preferred to keep shipping cost and transit risk down; international builders welcome if you can ship insured.
