    Example session with this skill installed

    I have two Asus TUF laptops and a Mac Mini. I want to build a small rack using slotted angle iron. How should I arrange them for best cooling and what Ubuntu settings do I need?

    • Read your context and instructions
    • Compiled the homelab server blueprint

    I have designed a layout that prioritizes the thermal needs of the TUF laptops while utilizing their internal batteries as a built-in UPS.

    Homelab Rack Blueprint: Project Twin-TUF Cluster

    1. Physical Specifications

    • Material: Slotted Angle Iron (Besi Siku Lubang)
    • Dimensions (HxWxD): 60cm x 45cm x 40cm
    • Number of Tiers: 2
    • Shelf Surface: Perforated metal mesh to allow the TUF bottom intakes to breathe.

    2. Tier Allocation

    • Top Tier (Compute & Networking):
      • Node 1: Asus TUF A15 (AI Worker) - Placed horizontally, lid closed, charging capped at 60% via BIOS/TUF Control.
      • Node 2: Asus TUF F15 (Media Server) - Placed horizontally, lid closed, 20% air gap from Node 1.
      • Network: 5-port Unmanaged Gigabit Switch tucked behind the Mac Mini.
    • Bottom Tier (Static Compute & Power):
      • Node 3: Mac Mini (Docker/DNS) - Centered for weight distribution.
      • Power: 8-outlet Surge Protector with individual switches for each node.

    3. Thermal & Cable Management Plan

    Airflow: Since TUF laptops exhaust from the sides and rear, mount one 120mm USB fan on the left and one on the right of the top tier to assist cross-breeze.

    • Cable Routing: Group power bricks on the bottom tier to keep heat away from the laptops.

    4. Headless Configuration (Ubuntu)

    To ensure the laptops do not suspend when the lid is closed, edit your configuration:

    
# Edit /etc/systemd/logind.conf
# Set HandleLidSwitch=ignore
sudo systemctl restart systemd-logind

    Next steps

    1. Measure your laptops to ensure the 45cm width provides the required 20% airflow buffer.
    2. Check BIOS settings on the TUF units for "Battery Health Charging" to limit capacity to 60%.
    3. Secure the perforated mesh to the iron frame using M6 bolts with wide washers.

    Connects securely to your tools. The creator never sees your data.

    About this skill

    The problem

    Designing a homelab involves complex trade-offs between space, thermal management, and power stability. Standard server racks are often too expensive or bulky for residential spaces, leading to overheating hardware and cable clutter.

    What it does

    • Generates structural blueprints for custom racks using cost-effective slotted angle iron.
    • Provides hardware-specific configurations for repurposing high-performance laptops into headless 24/7 server nodes.
    • Calculates thermal dissipation requirements and suggests fan placements for dense mini-PC clusters.
    • Optimizes power distribution, including BIOS-level battery health management for laptop-based nodes.

    Frameworks & tools

    Ubuntu Server, logind.conf, BIOS power management, Slotted Angle Iron hardware, and USB/12V thermal cooling systems.

    Why this beats prompting it yourself

    Standard LLMs often suggest enterprise-grade rack solutions that aren't practical for home environments. This skill applies specific engineering constraints for repurposed consumer hardware, ensuring laptops don't suffer from battery swelling and custom iron racks provide sufficient vertical airflow.

    Use cases

    • Building a multi-node AI compute cluster using repurposed gaming laptops.
    • Designing a compact, silent mini-PC rack for a small apartment closet.
    • Configuring Ubuntu Server nodes to run headlessly with lid-closed operations.
    • Planning power redundancy and cooling for a 24/7 home automation hub.

    Known limitations

    Does not provide electrical wiring diagrams for mains power or structural load-bearing certifications for industrial weight. Limited to Ubuntu Server software configurations.
