Glossary

PCIe link power management. Enabling it (where stable) lets the system reach deeper idle states; disabled or unsupported devices keep links awake and raise idle power.

See also: C-states (package C-states), Idle power

CPU low-power sleep states. Deeper C-states cut idle draw substantially; BIOS settings, ASPM, and certain add-in cards can block them and quietly inflate idle wattage.

See also: Idle power, ASPM (Active State Power Management)

An isolated process sharing the host kernel (Docker, LXC). Far lighter than a VM — the right default on RAM-limited mini PCs for most self-hosted services.

See also: Virtualization (VM), Docker

The most common container runtime for self-hosting. Lets a small mini PC run many isolated services with minimal overhead via images and compose files.

See also: Container

eMMC is slow soldered flash common in cheap mini PCs and thin clients; NVMe is fast M.2 SSD storage. Booting the OS from NVMe rather than eMMC is a major responsiveness upgrade.

See also: Mini PC

A personal server environment run at home for learning, self-hosting, or both. Mini-PC homelabs prioritize low idle power, silence, and small footprint over raw performance.

See also: Self-hosting, Mini PC

The layer that creates and runs virtual machines. Type 1 runs on bare metal (Proxmox, ESXi); type 2 runs atop an OS. Homelabs almost always use type 1.

Whole-system wattage at rest, measured at the wall. The number that actually drives a 24/7 homelab's running cost — and the one spec sheets almost never state honestly.

See also: TDP (thermal design power), Kill A Watt / power meter, C-states (package C-states)

Intel's Alder Lake-N family of efficient low-power CPUs. The N100 is the budget homelab default; N305 adds cores for heavier workloads; N97 sits between. All are E-core-only and very power-thrifty.

See also: TDP (thermal design power), Idle power, PassMark

An inline plug meter that measures real power draw at the wall. The only reliable way to know a build's true idle and load consumption.

See also: Idle power

A small-form-factor computer (NUC-style, mini-tower, or thin client) used as a low-power always-on homelab host. Trades expandability for size, silence, and idle efficiency.

See also: Thin client, Small form factor (SFF), Idle power

A 170x170 mm motherboard standard — the smallest common DIY form factor with a PCIe slot. Used for compact NAS and homelab builds needing one expansion card.

See also: Small form factor (SFF), Mini PC

A widely cited synthetic CPU benchmark. Useful for rough relative comparison between low-power chips, but not a substitute for testing the actual workload.

See also: Intel N100 / N305 / N97

A popular free Debian-based hypervisor combining KVM virtual machines and LXC containers in one web UI. The de facto homelab virtualization platform.

See also: Hypervisor, Container

Running your own services (media, DNS, automation, file sync) on hardware you control instead of a cloud provider. The core purpose of most mini-PC homelabs.

See also: Docker, Homelab

A size class of compact PCs and motherboards (Mini-ITX and smaller, USFF). The practical envelope for homelabs that must stay quiet and unobtrusive.

See also: Mini PC, Mini-ITX

The thermal envelope a CPU is rated for, in watts. A rough sizing guide, not actual consumption — real idle draw is usually far lower and total system power matters more.

See also: Idle power, Intel N100 / N305 / N97

An ex-enterprise terminal (HP t620/t630/t640, Dell Wyse) repurposed as a cheap, ultra-low-power homelab node. Excellent watts-per-dollar, limited RAM and storage expansion.

See also: Mini PC, Idle power

Running isolated guest operating systems on one host via a hypervisor (Proxmox, ESXi). Heavier and more flexible than containers; needs more RAM, which is the usual mini-PC bottleneck.

See also: Hypervisor, Container, Proxmox VE

An informal value metric weighing hardware cost against its idle power draw over a 24/7 lifetime. Used-thin-client builds usually win it; new mini PCs trade some efficiency for warranty and NVMe.
