Mini PC as ESXi node — N100 vs N305 comparison

Writing about what I test and deploy myself — vSphere, homelabs, cybersecurity hardening and AI in infrastructure. No theory, only things that work.

If you’re building a homelab on a budget, mini PCs running Intel N-series processors are hard to ignore. I’ve been running both the N100 and the N305 as ESXi 8 nodes for the past few months. Here’s what I found.

The contenders

ESXi 8 compatibility
#

Both processors install ESXi 8.0 U2+ cleanly. You will not need any custom ISOs or workarounds — just the standard VMware installer.

One thing to watch: NIC compatibility. Most mini PCs ship with Realtek NICs, which ESXi 8 no longer supports natively. You have two options:

  • Add a USB-to-Ethernet adapter (Intel I225-V chipset preferred)
  • Use the community VMware NIC driver fling — works but adds management overhead

RAM — the real decision factor
#

This is where the N305 wins clearly. The N100 is hard-capped at 16 GB. That sounds fine until you try running 4–5 VMs with any real workload — vCenter alone eats 14 GB.

The N305 supports 32 GB, which is the sweet spot for a single-node homelab running vCenter + 3–5 workload VMs.

Power and noise
#

The N100 is essentially silent and sips power. Under full ESXi load I measured 8–12W at the wall. The N305 runs at 18–25W under the same conditions — still very reasonable.

For always-on homelabs, the N100’s efficiency is genuinely attractive.

My verdict
#

  • N100 — best if you already have a vCenter elsewhere (or use free ESXi without vCenter) and want a cheap compute node. 16 GB cap is a real constraint.
  • N305 — the better all-in-one node. 32 GB lets you run vCenter + real workloads on a single box.

I’m running the N305 as my primary lab node and the N100 as a second compute host in a 2-node vSAN cluster. Works great.

What I bought

Total for a 2-node lab: under $500. Not bad.
