Best all-in-one computers with 16GB RAM

Top pick: Apple iMac 24-inch (M6). It's the all-in-one to beat — a sharp 4.5K Retina screen, Apple's newest chip, and a design that stays quiet and tidy on a desk. It's the one I'd buy for everyday work, photos, video calls and creative apps, as long as macOS suits you.

Who the others suit:

• HP OmniStudio 27-inch — a bigger 27-inch canvas for Windows users who want more screen for spreadsheets and multitasking.
• Dell QC24250 — a plain, business-grade Windows machine; sensible if you want a familiar office setup.
• 27" Touchscreen All-in-One (i5, 16GB, 1TB) — touch input and lots of storage for a Windows household.
• 27" V470 FHD Touch — a budget-friendly touchscreen all-in-one for light tasks.
• Lenovo ThinkCentre Neo 50a 27" Touch — a sturdy touchscreen office machine; check the memory listing, since it's soldered and not upgradable.

Skip the cheap no-name 24-inch models: they cut corners on the screen and build.
