Homelab TCO & Power Planner
Build a web app that tells self-hosters whether keeping old parts is actually cheaper than buying fewer newer components. The product would estimate power draw, accessory costs, replacement risk, and break-even timelines from a simple hardware inventory.
Pourquoi c'est important
You get a pile of free or cheap parts and feel like you just saved a fortune, but the excitement fades once you realize the machine may run hot, consume far more electricity than expected, and still need extra cards or better cooling to be usable. You are stuck doing rough math in your head or searching scattered opinions to answer a basic question: is this setup actually economical to run all year? Existing community advice helps in fragments, but it does not give you a grounded total-cost view tied to your exact hardware mix, storage count, and intended workloads.
- · Conçu pour Budget-conscious self-hosters and NAS hobbyists deciding whether to reuse old desktops, CPUs, and hard drives for always-on home servers..
- · Monétisation la plus probable : Freemium.

Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1Users may trust their own rough estimates or free advice more than a paid planner, especially if the savings appear small.
- 2Accurate power modeling across old components is noisy, so recommendations may feel generic unless the database becomes very detailed.
- 3The tool could be used once during setup and then abandoned, creating weak retention unless ongoing monitoring is added.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
Cost anxiety was a major theme. Around half a dozen comments focused on electricity usage, especially for multiple spinning drives and older AMD processors that are known to be inefficient. Several replies also highlighted hidden accessory costs such as controller cards and cooling, and one direct comparison suggested that buying a single larger drive may be smarter than running many old ones. This points to a concrete planning gap with clear financial consequences.
