====== Old Laptops and Desktops =====

Repurpose old computers as capable servers.

> //Even 5-10 year old hardware can run modern web services effectively.//

===== Overview =====

Old laptops and desktops are excellent candidates for home servers. They often have adequate RAM and CPU, built-in battery provides UPS functionality, and are usually free or very cheap.

===== Advantages =====

  * **Cost**: Often free or very cheap compared to new hardware
  * **Performance**: Usually have adequate RAM and CPU for basic services
  * **Power backup**: Built-in battery provides UPS functionality
  * **Expandability**: Easy to add storage via USB
  * **Availability**: Many people have old devices collecting dust

===== Considerations =====

  * **Power consumption**: Higher than purpose-built servers (15-60W)
  * **Performance**: May need SSD upgrade for better responsiveness
  * **Cooling**: Can be an issue in enclosed spaces
  * **Battery life**: 24/7 operation may shorten battery lifespan
  * **Noise**: Laptop fans can be audible in quiet environments

===== Real-World Examples =====

**Minimal specs that work:**
  * Intel Pentium with 2GB RAM can run basic web services
  * Core 2 Duo with 4GB RAM handles lightweight Docker containers

**Capable setups:**
  * i3-7020U with 20GB RAM outperforms $6/month VPS in benchmarks
  * Core i5 with 16GB RAM can host small Minecraft server alongside Docker containers

===== Hardware Requirements =====

**Minimum viable:**
  * CPU: Dual-core 64-bit processor (Intel Core 2 Duo or later)
  * RAM: 2GB minimum, 4GB recommended
  * Storage: 128GB minimum, SSD strongly preferred
  * Network: Ethernet port preferred over Wi-Fi

**Ideal for multiple services:**
  * CPU: Quad-core processor
  * RAM: 8GB or more
  * Storage: 256GB+ SSD
  * Network: Gigabit Ethernet

===== Setup Tips =====

  * Replace HDD with SSD for significant performance improvement
  * Consider adding more RAM if slots are available
  * Ensure adequate ventilation for 24/7 operation
  * Disable sleep mode and screen timeout in BIOS/OS
  * Set lid close action to "do nothing" for laptops
