Ready to start your homelab journey but not sure where to begin? This guide covers hardware choices, software essentials, and the mindset that will help you succeed.

What is a Homelab?​

A homelab is your personal IT playground at home. It can be:

  • A single Raspberry Pi running Pi-hole
  • An old laptop as a Docker host
  • A rack full of enterprise servers
  • Anything in between!

The goal isn't having the biggest setup—it's learning, experimenting, and running services you control.

Choosing Your Hardware​

Option 1: Repurposed Hardware (Budget)​

Old PC/Laptop:

  • Cost: $0-200
  • Quiet, low power
  • Great for starting out

Mini PC (Dell Micro, Lenovo Tiny):

  • Cost: $100-300 used
  • Very efficient
  • Small footprint

Option 2: Used Enterprise (Performance)​

Dell PowerEdge R720/R730:

  • Cost: $200-500
  • Tons of RAM/CPU
  • Loud, power-hungry

HP ProLiant DL380:

  • Similar to Dell
  • Great community support

Option 3: Purpose-Built (Balanced)​

Intel NUC:

  • Cost: $300-800
  • Silent operation
  • Low power (15-30W)

Custom build:

  • Full control
  • Can be optimized for use case

My Recommendation for Beginners​

Start with what you have, then:

  1. Month 1-3: Old PC/laptop or Raspberry Pi
  2. Month 4-6: Mini PC or used server
  3. Year 2+: Purpose-built based on needs

Don't buy servers before you know what you need!

Essential Software Stack​

Foundation​

LayerOptions
OSUbuntu Server, Proxmox, TrueNAS
ContainersDocker, Portainer
Reverse ProxyNginx, Caddy
SSLLet's Encrypt, Certbot
Backuprsync, Borg, Duplicati

Must-Have Services​

  1. Pi-hole or AdGuard - Network-wide ad blocking
  2. Portainer - Docker management UI
  3. Uptime Kuma - Service monitoring
  4. Homepage/Homarr - Dashboard for all services

When You're Ready​

  • Nextcloud - File storage
  • Jellyfin - Media server
  • Arr stack - Media automation
  • Tailscale - Remote access

Networking Basics​

Start Simple​

Level Up With VLANs​

VLAN 10: Management
VLAN 20: Servers
VLAN 30: IoT devices
VLAN 40: Guest network

Requires managed switch + VLAN-aware router.

First Day Checklist​

  1. Install OS (Ubuntu Server or Proxmox)
  2. Set static IP
  3. Enable SSH
  4. Install Docker
  5. Deploy Portainer
  6. Set up Pi-hole
  7. Configure backups

Budget Breakdown​

Ultra Budget ($0-100)​

  • Raspberry Pi 4 4GB: ~$60
  • SD Card: ~$15
  • Power supply: ~$10
  • Case: ~$15

Running: Pi-hole, Home Assistant, small services

Starter ($200-400)​

  • Used Mini PC: ~$200-300
  • 16GB RAM upgrade: ~$50
  • 500GB SSD: ~$50

Running: Docker host with 10-20 containers

Intermediate ($500-1000)​

  • Used Dell R720: ~$300
  • RAM upgrade (64-128GB): ~$100-200
  • SSDs for VMs: ~$200
  • UPS: ~$150

Running: Proxmox with multiple VMs, serious storage

Common Mistakes to Avoid​

1. Buying Too Much Hardware​

"I'll need 128GB RAM" - You probably won't. Start small.

2. No Backup Strategy​

If it's not backed up, it doesn't exist. Set up backups on day one.

3. Over-Engineering​

Don't build Kubernetes for 5 containers. Docker Compose is fine.

4. Ignoring Power Costs​

That $200 server could cost $50/month in electricity. Calculate TCO.

5. No Documentation​

Document as you go. Future you will thank present you.

Mindset Tips​

  1. Break things - It's how you learn
  2. Start simple - Complexity comes later
  3. Join communities - Reddit r/homelab, Discord servers
  4. Set goals - Know why you're building
  5. Have fun - It's a hobby, not a job

Resources​

What's Next?​

Once you've got the basics:

  1. Install Docker
  2. Set up Proxmox
  3. Configure Networking
  4. Deploy a media server
