Compare the best mini PC for a home server in 2026: real prices, idle watts, RAM ceilings, and Proxmox fit vs a Raspberry Pi, with power-cost math.

Free, ZFS-grade TrueNAS SCALE versus Unraid's mixed-drive parity array (from $49) — with the two 2026 changes that reshape the choice: OpenZFS RAIDZ expansion and Unraid's native ZFS pools. A first-hand decision table to match a NAS OS to your actual drives and budget.

WireGuard wins on speed, simplicity, and battery; OpenVPN wins on firewall-bypass over TCP 443 — and OpenVPN's kernel-space DCO has largely closed the old throughput gap. A first-hand decision table and a real WireGuard config to help you pick the right protocol for a self-hosted VPN.

Plex's 2025-2026 price hikes put remote streaming and hardware transcoding behind a paywall — and tripled the Lifetime Pass to $749.99. Running both on a Proxmox homelab, here's a first-hand decision table on cost, transcoding, privacy, and which media server actually fits your setup.

Germany's 2027 pension reform replaces Riester with the Altersvorsorgedepot, letting savers hold ETFs with an optional (not mandatory) capital guarantee. A worked subsidy table shows a parent of two paying €1,800/year receives €1,140 back in state top-ups.

A worked, original cost table shows what Hausratversicherung actually costs for 60/90/120 m² German flats, built from the 650 €/m² Versicherungssumme rule and real published Tarifzone rates — showing why an identical policy can cost 2–4x more depending only on postcode.

Betriebliche Altersvorsorge lets you convert salary into a workplace pension tax-free up to €8,112 in 2026, with a mandatory 15% employer top-up. The catch: full income tax and full statutory health and long-term-care contributions apply when the Betriebsrente pays out later.
