The laptop idles at 10-15W and peaks at 20-30W under Jellyfin transcoding load, costing about 10kWh/month alongside a NAS. The A5 mini PC is far more efficient (4-6W idle, 4-4.5kWh/month) but costs $220 upfront, meaning it would take roughly 220 months (18 years) to recoup the cost through power savings versus the free laptop. The workstation, at 135-150W, is ruled out entirely for 24/7 use. Conclusion: acquisition cost outweighs efficiency gains, so the free old laptop remains the better financial choice. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is it cheaper to keep using an old laptop as a home server or buy a more power-efficient mini PC? Keeping a free old laptop is usually cheaper overall. An 8-year-old Dell Latitude 7480 (Core i5-6300U) running as a 24/7 Debian server draws 10-15W idle and 20-30W under load, costing about 10kWh monthly, while a far more efficient mini PC like the A5 draws only 4-6W idle and consumes roughly 4-4.5kWh monthly. However the mini PC costs $220 upfront and saves only about $1 per month, meaning it takes around 220 months (18 years) to recoup that cost, so the free laptop remains the better financial choice despite worse efficiency. _daily.dev surfaces homelab cost-benefit writeups like this for anyone weighing hardware upgrades against power savings._ ### How much power does an idle home server with Jellyfin, Immich, and Nextcloud typically draw? An old business laptop (Intel Core i5-6300U, 12GB RAM) running Jellyfin, Immich, and Nextcloud as a bare-metal Debian server draws around 10-15 watts when idle, and rises to 20-30 watts under heavier load such as multiple Jellyfin streams with transcoding, where CPU usage exceeds 70%. A companion NAS used purely for bulk storage adds a similar 10-15 watts. _Homelabbers benchmarking real service loads against power draw can track comparisons like this on daily.dev._ ## Similar posts on daily.dev -
