All-in-One (AIO) computers represent a compelling paradox: they pack desktop-grade capabilities into a sleek, minimalist form factor, yet often demand compromises in upgradability and raw power. ZDNET's exhaustive testing of 2025's contenders reveals a landscape where elegance meets increasingly potent hardware, offering viable solutions for developers, designers, and office environments craving a clutter-free setup without sacrificing core functionality.

The Space-Saving Power Play

AIOs integrate the computer's internals directly behind the display, drastically reducing cable chaos and footprint. This makes them ideal for constrained spaces – developer pods, reception desks, home offices, or creative studios where a clean aesthetic matters. However, this integration comes at a cost: limited upgrade paths and often higher price points compared to traditional towers. Repairability is notoriously challenging, as ZDNET's June Wan notes, "internal parts are typically woven into the chassis, leaving little room for modification." Choosing the right configuration upfront is paramount.

ZDNET's Top Contenders: Performance Meets Polish

  1. The Benchmark: Apple iMac 24-inch (M4)

**Why it Leads:** Apple's latest iMac isn't just a pretty face. The M4 chip (especially in the 10-core CPU/GPU configuration tested) delivers exceptional performance for coding, light video editing, and multitasking, effortlessly handling macOS Sequoia and new AI features. The 24-inch 4.5K Retina display remains stunning, offering vibrant colors and sharp detail crucial for design work. The bundled Magic Keyboard with Touch ID and sleek design solidify its appeal. **The Catch:** The glossy screen can be reflective; a matte finish adds $200. Upgrading from recent M-series iMacs offers diminishing returns. Limited storage options on base models (256GB SSD) feel restrictive for large project files. **Ideal For:** Developers in Apple ecosystems, designers, students, and everyday users prioritizing a seamless, powerful, and beautiful desktop experience.

  1. Windows Powerhouse: HP OmniStudio X 32

Why it Stands Out: For Windows users needing screen real estate and discrete graphics, the OmniStudio X 32 is a revelation. Its massive 32-inch 4K display with 550-nit brightness and a matte finish is a visual treat, perfect for complex IDEs or multitasking. The inclusion of an NVIDIA GeForce RTX 4050 GPU is rare in the AIO space, enabling respectable light gaming and smoother 4K video editing than integrated solutions allow.
The Catch: The bundled peripherals are underwhelming; budget for better keyboard/mouse and potentially external speakers. Its size and weight (21.6 lbs) demand a sturdy desk.
Ideal For: Windows-centric developers, power users needing large screens for multi-monitor-like workflows, and creatives requiring capable GPU acceleration without a bulky tower.

  1. The Value Champion: Asus M3402WFA
    Budget Doesn't Mean Basic: Proving AIOs can be affordable, the Asus M3402WFA packs a surprising punch. Its near-bezel-less 24-inch Full HD anti-glare display maximizes screen space. The AMD Ryzen 5 7520U, 16GB RAM, and 512GB SSD handle everyday development tasks and office work smoothly. Dolby Atmos-enhanced audio is a notable bonus for its price class.
    The Compromise: Performance is strictly for light-to-moderate workloads; don't expect heavy compiling or complex rendering. The 720p webcam is basic, though AI features help somewhat.
    Ideal For: Budget-conscious developers, home offices, students, and secondary workstations where cost and simplicity trump raw power.

  2. The Creator's Canvas: Lenovo Yoga AIO 9i
    Flexibility Defined: This AIO breaks the mold with its unique flexible hinge, allowing the 27-inch QHD touchscreen to swivel, tilt, and even lay nearly flat – a boon for digital artists and designers sketching directly on screen. Configurations with Intel Core Ultra 7 chips and RTX 4050 graphics offer solid creative performance. Dolby Atmos audio enhances the experience.
    The Consideration: The premium for flexibility and touch is high. Its weight (18.5 lbs) and complex hinge mechanism require careful placement.
    Ideal For: Digital artists, UX/UI designers, content creators who value direct screen interaction and adaptable ergonomics.

The Windows 11 Imperative

A critical note for all Windows AIOs: Microsoft ends support for Windows 10 on October 14, 2025. Every recommended Windows AIO here ships with Windows 11, ensuring ongoing security updates and compatibility – a non-negotiable factor for professional and secure development environments.

Beyond the Hype: Is an AIO Right for You?

The allure of a clean desk is undeniable, but AIOs demand careful consideration. They excel in space efficiency and integrated design but lock you into specific hardware configurations for their lifespan (typically 5-8 years). For developers needing frequent RAM or storage upgrades, or enthusiasts craving the absolute peak performance from the latest GPUs, a traditional tower remains the pragmatic choice. However, for those prioritizing a minimalist, powerful, and aesthetically cohesive workstation where the display is the computer, the 2025 AIO lineup offers compelling, surprisingly capable options that finally blur the line between form and function.
