Written 22 Aug 2026. Specs from the maker pages linked below. Prices from those stores. I haven't used these.
Buy a new or Synology-certified DS224+. Skip random “renewed.”
Official Synology Certified Refurbished exists. Amazon Renewed is third-party restore, not Synology CPO. The clean US buy on 22 Aug 2026 is a new diskless DS224+ at $299.99.
Official CPO: 2-year Synology warranty, 30-day returns, new panels and accessories (power adapter is refurbished), not eligible for Extended Warranty Plus. The live program page is the EU storefront. US SKU stock was not a populated cart on the US product page when fetched. A Newegg “Refurbished: DS224+” listed 24 Jul 2026 is sold by “Synology America Corp Marketplace”, treat as a maybe. Confirm seller and price; the page showed the $299.99 new band, not a clear CPO discount.
New DS224+ diskless: Intel Celeron J4125, 2 GB (max 6 GB), 2× 1GbE. B&H $299.99. synology.com US MSRP $299.99 (Frontdesk Review, 27 Jun 2026). Access 14.69 W, HDD hibernation 4.41 W, noise 22 dB(A), 60 W 100–240 V brick, 2-year, Extended Warranty Plus in NA/EU. Those are maker numbers with Synology HDDs.
HPE Renew is a channel/VAR program. There was no live closet switch or ProLiant CPO page with a clean retail cart on 22 Aug 2026. There is not one to link. Amazon Renewed OptiPlex / EliteDesk is also not official HP or Dell CPO.

Skip
Skip Amazon Renewed as “official CPO.” It is not. Skip used eBay Synology lots as the default: that temptation is the UGREEN vs used Synology note if you actually need 10G. Skip inventing an HPE Renew closet switch. First-NAS shortlist remains first NAS. Used-vs-new rule: here.
