My First Homelab PC: Meet “Lil Beast” – Lenovo 510s with i5-8400

I’ve always wanted to start a homelab, and now I finally have the hardware to make it happen. Recently, I picked up a Lenovo Ideacentre 510s for just $80. It comes with an Intel i5-8400, 8GB RAM, and a 512GB SSD. Prices for PC parts have gone up because of the AI craze, so finding this deal felt amazing. I call this little machine Lil Beast.

How This Price Compares

To give you context, similar used desktop PCs with an i5‑8400, 8 GB RAM, and SSD typically range from $150 to $300 second‑hand:

  • Refurbished Dell OptiPlex 3060 SFF (i5‑8400, 8 GB, 512 GB SSD) sells for around $240
  • eBay listings show i5‑8400 desktops with 8 GB RAM for $120–$200

That puts my $80 deal significantly below average, making Lil Beast a budget-friendly gem.

Why I Bought It

I wanted something affordable and reliable for homelab experiments. The Lenovo 510s is compact, energy‑efficient, and powerful enough for everyday tasks. It’s a fantastic entry point for anyone wanting to dive in. Besides, I need a CPU with a minimum UHD Graphics 630 for media purposes.

Lil Beast is almost 6 years old now. But it is still going strong.

Specs at a Glance

  • CPU: Intel i5‑8400 (6 cores, strong multitasking performance)
  • RAM: 8 GB DDR4
  • Storage: 512 GB SSD
  • Price: $80 (second‑hand deal)
RAM is originally 4GB based on sticker. Perhaps, the previous owner has upgraded it?

What I Plan to Do

This machine is my homelab foundation:

  • Virtualization: lightweight VMs for testing
  • Media Server: Jellyfin for streaming
  • Automation: Home Assistant for smart home control
  • AI Experiments: running local LLMs (if the hardware allows, which I doubt)

Homelabs aren’t just for enthusiasts. They give you control, flexibility, and a learning playground. Lil Beast will improve my quality of life by centralizing services, automating tasks, and offering endless tech exploration.

My Takeaway

If you’re thinking about starting a homelab, don’t wait for perfect specs. Start small, start cheap, and start today. Lil Beast may not be top-tier, but for $80 it’s more than enough to get the ball rolling.

Lil Beast has a disk reader! Though, I don’t know if I will ever need it…
