A Dell All-in-One packs the whole computer into the back of the display, so you get a full desktop with one power cable and no separate tower. The current range spans the consumer Inspiron 24 and 27 and the newer Dell 24 / Dell 27 All-in-One models, plus commercial Dell Pro All-in-One units (the line Dell renamed from OptiPlex in its 2025 Dell / Dell Pro / Dell Pro Max rebrand). Most ship with a current Intel Core Ultra or Core i5/i7 processor, DDR5 memory, an NVMe SSD and a 24-inch or 27-inch FHD or QHD screen, with touch available on several. It is a tidy, low-clutter setup for home, study, reception desks and office work. Availability and configuration vary, so check each Dell AiO's spec sheet before you order.
