I work with enterprise networking gear every day — Juniper EX switches, Aruba APs, Check Point firewalls. So when it came time to build a home lab, I had two requirements: it needed to feel like real infrastructure, and it needed to not break the bank. Here's what I settled on.
The Core: A Managed Switch
The heart of any home lab is the switch. I went with the TP-Link TL-SG108E — an 8-port gigabit managed switch for about $35. Yes, you can spend $300+ on a used enterprise switch, but for most home labs, you don't need 10GbE or PoE++ out of the gate. The TP-Link gives you VLAN support, QoS, port mirroring, and a simple web interface. It's silent, runs cool, and sips power.
When you outgrow it (and you will), start watching eBay for used Aruba Instant On 1930 switches — they're enterprise-lite and show up for ~$150 used. That's what I run at my desk now.
The Server: Refurbished Mini PC
Instead of a full tower server that's loud and hot, grab a tiny PC. I use an HP EliteDesk 800 G4 Mini (Intel 8th-gen i5, 16GB RAM) that I found refurbished for ~$120. It sits behind my monitor, draws 15W at idle, and is silent.
It runs:
- Proxmox VE — Type 1 hypervisor, free, lets me run VMs and LXC containers
- Pi-hole — ad blocking for the whole network
- Jellyfin — media streaming (more on that soon)
- Headscale — self-hosted Tailscale control server (I wrote a guide on setting this up on Synology)
- LibreNMS — network monitoring (because I'm a nerd and I like graphs)
Storage: Synology NAS
I run a Synology DS220+ with two 4TB drives in RAID 1. It's the foundation for my media library, backups, and Docker containers. The Synology ecosystem is worth the premium — DSM is genuinely good software, and the app ecosystem (Surveillance Station, Synology Photos, Active Backup for Business) adds functionality I'd otherwise need separate VMs for.
The Total
- TP-Link switch: $35
- HP EliteDesk mini: $120
- Synology DS220+ (no drives): ~$300
- Two 4TB drives: ~$200
- Used Aruba IAP-315 (for learning): ~$40
Total: ~$700 — and half of that is the NAS storage. Without the NAS, you can build a very capable homelab for under $200 if you already have an old laptop or desktop lying around.
What I'd Do Differently
Skip the consumer router's built-in switch ports. Use a real managed switch — even a cheap one — so you can learn VLANs, STP, and link aggregation. Those skills transfer directly to enterprise gear, and it's way more satisfying when things break and you have to fix them.
