ArgoCD runs GitOps on k3s: install it, lay out the repo, and manage apps declaratively from Git. Covers sealed-secrets, sync waves, and app-of-apps.

Build a three node Kubernetes cluster on mini PCs with k3s: static IPs, firewall ports, local-path storage, and a first deployment that actually answers.

Remote console without IPMI: compare PiKVM, JetKVM, and DIY solutions, hardware costs, BIOS access, latency, and when to pick each.

Pick the right rack for your homelab: open frame vs 4-post vs wall-mount. Cable management, noise, and space trade-offs explained.

Used SFP+ gear turns 10GbE from a $5k fantasy into a $200 build. Mellanox NICs, the MikroTik CRS305 switch, DAC cabling, and where the savings stop.

Pick the right IT-mode HBA for ZFS: LSI 9211-8i vs 9300-16i vs 9400 series. Flash firmware, avoid RAID controllers, navigate expanders and PCIe lanes.

Remote management 101: IPMI, iDRAC, iLO basics, network isolation, security, and redfish. Why BMC matters when you can't reach the power button.

Calculate true energy costs: watts, kWh, BTU output, and 5-year TCO for homelab hardware swaps. When efficiency pays back.

Used enterprise-grade managed switches under $100: Aruba, Brocade, MikroTik picks, VLAN setup, wattage, and gotchas for home lab networks.

Noctua fans, IPMI curves, and undervolting techniques to make rackmount servers bedroom-quiet without thermal compromise.

Master UPS sizing math: VA vs watts, runtime calculations, battery replacement costs, NUT monitoring, and when EcoFlow beats enterprise hardware.

Raspberry Pi 5 vs Mini PC: when ARM wins, real costs with NVMe HATs, power consumption, performance, and ecosystem trade-offs for your home lab.
