You can read about Kubernetes for six months and still freeze the first time a node flips to NotReady at 2 a.m. Cloud free tiers help, but they expire, they nickel-and-dime you the moment you leave something running, and they hide the layer most engineers are weakest on: the network underneath. The fastest cure is also the least glamorous one. Build a small home lab and break things on hardware you own.
This is the lab I'd build today: enough compute to run a multi-node Kubernetes cluster under Proxmox, plus the routing and switching gear to practice the networking that shows up in interviews and 3 a.m. incidents. For each role I've picked a budget on-ramp and a high-end upgrade, so you can start cheap and grow into it.
The compute
1. Minisforum MS-01: the lab workhorse
I ran a Minisforum box as my home lab for years and never found a reason to look elsewhere, so the MS-01 is where this build starts. The config I'd call the hero is the Intel Core i9-13900H workstation model with vPro enterprise support. It ships with 32 GB of DDR5 and a 1 TB SSD, and the chassis takes up to 96 GB. The I/O is what you won't find anywhere else this size: dual 10GbE SFP+, dual 2.5GbE RJ45, two USB4 ports, HDMI, and a full PCIe 4.0 x16 slot, plus room for three M.2 (2280/22110) or U.2 SSDs.
That spec sheet is why it anchors the lab: install Proxmox, split it into VMs, and run a three-node Kubernetes control plane on one quiet box, with NIC and PCIe passthrough to practice on. The x16 slot even takes a GPU or a second NIC, so it scales when you do. It's the closest thing to a rack server that fits on a shelf.
Best for: anyone who wants one machine to do everything. Watch for: it's the priciest item here, so if you're just starting, begin with the Pi below and add this when you outgrow it.

2. CanaKit Raspberry Pi 5 Starter Kit PRO (8GB): the grab-and-go node
If the MS-01 is the dream, the Raspberry Pi 5 is the "start this weekend" pick, and a kit saves you sourcing parts piecemeal. This CanaKit Starter Kit PRO bundles the 8 GB Pi 5 with its Turbine Black case and active cooling, a power supply, and a 128 GB card, so it boots straight out of the box. The Pi 5 runs a quad-core Arm Cortex-A76 at 2.4 GHz and adds PCIe via an M.2 HAT, a clear step up from the Pi 4. Buy two or three and you've got a physical cluster for k3s, the tactile version of learning Kubernetes where you can yank a node out of its case and watch the scheduler react.
Best for: first-time lab builders who'd rather not chase a case, power supply, and SD card separately. Watch for: it's Arm, so the occasional container image differs from x86, and it won't carry heavy workloads, but as a teacher it's unbeatable.

The network around it
A DevOps lab isn't only compute, which is where most gear lists stop. The skills that separate a junior from an SRE live in the network layer: VLAN segmentation, firewall rules, static routes, NAT, QoS. Managed gear lets you wall the lab off from your home network, mirror traffic, and see what your apps sit on. You want a managed router and a managed switch, with a budget pick and an upgrade for each.
3. MikroTik hEX S (RB760iGS): budget router
The cheapest legitimate way to learn enterprise-grade routing. The hEX S gives you five gigabit ports plus an SFP cage and the full RouterOS v7 feature set: firewalling, VLANs, BGP, OSPF, VPNs, QoS, at roughly gigabit line-rate in fastpath, with hardware IPsec. (Skip the cheaper plain hEX/RB750Gr3; it chokes around 380 Mbps once you add rules.)
Best for: learning networking on the same OS used in production WISP and SMB networks. Watch for: RouterOS has a learning curve, and climbing it is the point.

4. MikroTik RB5009UG+S+IN: high-end router
When the hEX S's CPU becomes your ceiling, this is the upgrade. A quad-core 1.4 GHz Arm chip with hardware-accelerated routing, 1 GB of RAM, seven gigabit ports, a 2.5GbE port, and a 10G SFP+ cage. That SFP+ uplink is the reason to buy it: it ties straight into the MS-01's 10GbE and the switch below for a true 10-gig core. It's rack-mountable too; four fit in 1U.
Best for: a home lab that's turned into your main network, or anyone who wants to push past gigabit. Watch for: overkill if you're only running a couple of Pis; start smaller and add it later.

5. TP-Link TL-SG108E: budget switch
The friendly on-ramp to managed switching. Eight gigabit ports, support for dozens of VLANs, QoS, and port mirroring, all driven from a simple local web UI (no cloud account). For the price of a couple of lunches you can practice VLAN tagging and segmentation without ever touching your main network.
Best for: your first taste of managed networking. Watch for: it's a learning switch, not a 10-gig fabric, which is what the next pick is for.

6. MikroTik CRS310-1G-5S-4S+IN: high-end switch
This is the 10-gigabit heart of a serious lab: four SFP+ ports at 10GbE for your fast fabric, plus five 1G SFP ports and a gigabit RJ45 for everything else, running SwitchOS or RouterOS. Wire the MS-01's two SFP+ ports, a NAS, and the RB5009 into the 10G ports and your storage and VM traffic moves at 10 gig, with ports to spare.
Best for: stitching the high-end build into a 10-gig fabric with room to expand. Watch for: you'll want SFP+ modules or DAC cables to match, so budget for those.

Putting it together
You don't need all six at once. Two sensible builds:
- The starter lab: a couple of Raspberry Pi 5 kits, the TL-SG108E switch, and the hEX S router. A modest one-time spend that teaches you
k3s, VLANs, and routing, everything a junior DevOps or SRE role expects. - The dream lab: the Minisforum MS-01 running Proxmox, the RB5009 router and CRS310 switch tied together at 10GbE, with a Pi or two for edge nodes. A miniature datacenter you can run production workloads on.
Start where your budget is today and add pieces as you outgrow them. That's the whole point of buying gear with a clear upgrade path. Those hours become hands-on interview answers, the kind that get offers.
