Best 27-inch all-in-one desktop computers for home and office

Top pick: HP OmniStudio All-in-One 27" (Core Ultra 7). It's the best balance for a home-and-office machine: a current Intel Core Ultra 7 with 10 cores, a 27-inch FHD screen, and enough headroom for spreadsheets, video calls and a dozen browser tabs at once. HP sells it directly and several other stores carry it, so support and warranty are straightforward.

Who the others suit:

• Dell 27 All-in-One (ec27250) — the sensible everyday choice if you mostly do email, documents and web work and want a familiar business-grade brand.
• Lenovo ThinkCentre 27" FHD touchscreen — best for a shared or front-desk setup where people tap through forms and kiosk-style apps.
• Lenovo IdeaCentre 27" touchscreen — a roomier 1 TB drive for photo libraries and local backups.
• HP 27" all-in-one (27-cr0012) — an IPS panel and an IR camera, so it suits video-heavy work and Windows Hello sign-in.
• Dell 27 touchscreen all-in-one — the step up if you edit photos or video and want discrete graphics.
• Budget 27" models (V470, Suevery) — fine for light home use, but expect a plainer screen and less future-proof performance.

Skip the Lenovo Yoga AIO 27 for now: no store currently sells it at a price we could confirm.
