How To Choose The Best 27 Inch All-in-One Computer
Picking a 27-inch all-in-one is about finding the right mix of processing power, memory, storage, and display quality for how you actually use your computer. Here are the three specs that matter most.
Processor Speed and Core Count
The processor (the CPU, or the “brain” that runs your programs) determines how fast your computer handles tasks. Look for at least an Intel Core i5 or AMD Ryzen 5 for smooth everyday use like web browsing and office work. If you edit photos, do video work, or run heavy spreadsheets, step up to a Core i7 or Ryzen 7 for noticeably faster performance when multitasking.
Memory and Storage
RAM (your computer’s short-term memory) is what keeps multiple programs running smoothly. For most people, 16GB of RAM is a great starting point. If you keep many browser tabs and applications open at once, 32GB is better. For storage, a solid-state drive (SSD) is much faster than a traditional hard drive — aim for at least 512GB, or 1TB if you store lots of files and photos.
Display Quality and Extra Features
A 27-inch Full HD (1920×1080) screen is standard and plenty sharp for daily work. Touchscreen models add convenience if you like using gestures, but they also cost more. Also check for a built-in webcam (preferably with a privacy shutter), good speakers, and enough USB ports for your mouse, keyboard, and external drives.

In‑Depth Reviews
1. Acer Aspire C27-1700-UA91 AIO Desktop
A smart-balanced daily computer that handles work and streaming without costing a fortune.
For most people, this Acer hits the balance. You get a 27-inch Full HD IPS display with a 91% screen-to-body ratio — meaning the bezels are slim so the picture dominates your desk — and a 12th Gen Intel Core i5-1235U processor that tops out at 4.4 GHz. That is fast enough for web browsing, office suites, and even photo editing, as buyers report it runs Roblox, Valorant, and Fortnite at full graphics settings without issue. The 16GB of DDR4 memory (your computer’s short-term workspace for running apps) and 512GB NVMe SSD (a very fast type of solid-state drive) give you smooth multitasking and quick boot times.
Its cache memory (a small, super-fast data stash right on the processor) of 12 MB is half the size of the Lenovo IdeaCentre’s 24 MB, so the Acer is not built for extreme multi-app workloads the way the Lenovo is. But the Acer includes a 5.0 MP (megapixel — a measure of camera detail) webcam with a privacy cover, dual microphones, and Wi-Fi 6 (the latest, fastest Wi-Fi standard), making it a solid choice for video calls. Owners mention the setup is quick — one owner said it was a “fast, efficient upgrade from old PC” — and the picture is beautiful with no pixelation.
What works well
- Clean, slim design with narrow bezels for an rich view
- 16GB RAM and 512GB SSD provide responsive everyday performance
- Wi-Fi 6 and Bluetooth 5.2 keep wireless connections fast and modern
What to consider
- No touchscreen, which some users may prefer for navigation
- 12 MB cache means it trails higher-end models in heavy multitasking
Reach for this if: you want a well-rounded, capable all-in-one for everyday work, streaming, and light gaming without overpaying.
Look elsewhere if: you need a touch display or plan to run professional video editing and heavy data analysis all day.
2. ASUS V470 All-in-One V470VA-MS504T
A touchscreen all-in-one that brings a sharp display and solid storage at a mid-range price.
The ASUS V470 stands out with its 27-inch Full HD anti-glare touchscreen, letting you tap, swipe, and zoom directly on the display. Inside, an Intel Core i5-13420H processor (with a top speed of 4.6 GHz and 12 MB of cache) handles your day-to-day tasks smoothly. Paired with 16GB of faster DDR5 RAM — the newer, quicker type of memory compared to the DDR4 found in many rivals — and a roomy 1TB PCIe SSD, this machine feels snappy from the moment you unbox it.
Unlike the Acer above, this ASUS trades a larger SSD and touch capability for a slightly lower cache size. But reviewers appreciate the hidden webcam that tucks away when not in use, and one owner noted they swapped the included wired keyboard for a wireless one to move freely around the office. The AI noise-canceling technology helps clean up your voice during video calls, and the Dolby Atmos speakers deliver richer sound for music and movies than most built-in speakers in this class.
Touch trade-off: The display is not height-adjustable, and buyers mention ASUS pre-installs some bloatware you will want to remove.
Best for: someone who wants a touchscreen for quick interactions and needs a large 1TB drive without jumping to a premium price point.
skip it if: you need an adjustable-height stand or prefer a completely bloatware-free experience from the start.
3. HP 27 inch All-in-One Desktop PC 27-cr0012
Plenty of memory and a fast AMD processor for heavy multitaskers who keep dozens of tabs open.
If your workflow involves running many programs at once — spreadsheets, video calls, web browsers with 20+ tabs — this HP machine handles it well. It packs an AMD Ryzen 7 7730U processor with 16 MB of cache, 32 GB of DDR4 RAM, and a 1 TB solid-state drive. That RAM capacity beats the 16GB found on the Acer and ASUS models, so you can keep more apps open without slowdowns. One buyer described it as a “beast” that never hesitates even with many browsers and tabs active.
It also features a tiltable pop-up privacy camera and dual-array microphones with noise reduction for clear video calls. However, a significant caveat emerged in the reviews: one owner reports the computer shuts off randomly and needs to be unplugged and replugged to power back on. This appears to be an overheating-related safety trip, and it is something to watch for. The slim three-sided micro-edge display gives you up to a 90% screen-to-body ratio, and the white design looks clean on a desk.
Strengths
- 32GB RAM and Ryzen 7 processor deliver excellent multitasking headroom
- Pop-up privacy camera with noise reduction for professional video calls
- 1TB SSD provides fast storage and loads of space for files and photos
Potential risk
- Multiple units reported random shutdowns that require unplugging to reset
- No touchscreen option on this model
Ideal for: power users who need 32GB of RAM and a strong AMD processor for demanding office work.
Be cautious if: reliability is your top priority — the shutdown reports suggest some units may have overheat protection issues.
4. Lenovo IdeaCentre 27″ All-in-One Desktop PC
A powerful 10-core workhorse with professional-grade features for demanding users.
This Lenovo brings serious horsepower. The Intel Core i7-13620H processor has 10 cores (6 performance and 4 efficiency) with 16 threads and a max speed of 4.9 GHz — that is 11% more top-end speed than the 4.4 GHz in the Acer C27-1700. Its cache memory is 24 MB, double the 12 MB in the Acer, meaning it handles heavy multitasking and data analysis with less slowdown. Paired with 32GB of DDR5 RAM and a 1TB PCIe SSD, this machine is built for content creation, video editing, and professional workloads.
Buyers praise its speed — one owner upgraded from an old Windows 10 HP and called this machine “very fast” and easy to set up. But there is a design trade-off: one reviewer points out that the ports are located under the thin bottom bezel, which is blocked by the stand. To access them, you have to lay the screen face-down and pull the stand back, which is cumbersome. The Luna Grey finish looks sleek, and the HARMAN speakers provide solid audio for calls and entertainment.
Performance highlights
- Core i7-13620H with 4.9GHz speed and 24MB cache beats most rivals in raw power
- 32GB DDR5 RAM and 1TB SSD provide fast, responsive multi-tasking
- Windows 11 Pro adds enhanced security and business features
Design drawbacks
- Rear ports are hard to reach behind the stand, requiring awkward access
- Some buyers dislike the build quality of the screen frame
Best for: professionals who need maximum processing power and RAM for editing, data work, and heavy multitasking.
Consider other options if: you frequently plug and unplug devices and want easy port access.
5. Dell 27 All-in-One Desktop EC27250
A premium touchscreen all-in-one with dedicated graphics and a clever keyboard storage design.
Dell’s EC27250 combines a 27-inch Full HD IPS touch display with a dedicated NVIDIA GeForce MX570A graphics card with 2GB of GDDR6 memory — a rare feature in all-in-ones that helps with creative apps and light gaming. The Intel Core 7 processor 150U and 32GB of DDR5 RAM keep everything moving fast, while the 1TB SSD offers ample storage. The display covers 99% of the sRGB color space, so photos and videos look vivid and true-to-life.
A standout design detail is the stand that lets you stow the keyboard underneath, keeping your desk clear. The 5MP infrared (IR) camera uses invisible light to recognize your face and supports Windows Hello for secure, password-free login. It also has a pop-up privacy shutter. Buyers love the “crisp picture” and deep bass sound, and one noted the large display was a huge upgrade from a 14-inch laptop. However, some users report a limited number of USB ports, and one reviewer noted the keyboard was missing a connector and support was hard to reach.
Why it stands out
- Dedicated NVIDIA GeForce MX570A graphics for better creative and light gaming performance
- Keyboard storage under the stand saves desk space
- 5MP IR webcam with Windows Hello for fast, secure logins
Possible issues
- Some units have missing USB connectors or keyboard problems
- Onsite service is included, but support responsiveness has been questioned
Perfect for: creative professionals and anyone who wants a touchscreen with dedicated graphics and a clean, organized desk.
Not for: users who need many USB ports immediately available or want a budget-friendly option.
6. HP All-in-One 27″ Touchscreen Desktop Computer
Maximum everything — 64GB RAM, 4TB storage, and a touchscreen for users who settle for nothing less.
This is the top-end machine in the lineup, designed for someone who wants the highest specs available without moving to a workstation tower. It packs an Intel Core Ultra 7-155U processor (12 cores), a massive 64GB of DDR5 RAM, and a 4TB solid-state drive — enough memory and storage to run multiple virtual machines, huge databases, or professional video editing timelines without ever thinking about space. The 27-inch Full HD IPS touchscreen lets you interact directly with the display, and the three-sided micro-edge bezel boost the viewing area.
Customers note it is “blazing fast” — one reported loading Photoshop in two seconds — and excellent for audio production and video editing with no lag. The height-adjustable stand helps you find a comfortable ergonomic position, and the HP True Vision FHD IR camera supports facial recognition login through Windows Hello. One buyer mentioned the built-in soundbar on the bottom of the screen is a nice addition for quality audio. The main downsides are the premium price and the included keyboard, which some users with larger hands found cramped.
Top-tier advantages
- 64GB DDR5 RAM and 4TB SSD are class-leading by other all-in-ones in this group
- Height-adjustable touchscreen with FHD IPS panel for flexible ergonomics
- Face recognition login and Zoom-certified hardware for professional video meetings
Trade-offs
- Premium investment is justified only if you actually need the highest specs
- Keyboard design is polarizing — some users find it uncomfortable for large hands
Ideal for: power users, content creators, and professionals who run memory-intensive applications and want the highest storage capacity in an all-in-one.
Overkill for: anyone doing basic web browsing, email, and office work — you will pay for performance you will never use.
Understanding the Specs
Processor (CPU) and Cache Memory
The processor is the brain of your computer. Its speed (measured in GHz) and the number of cores determine how fast it can run programs. Cache memory (measured in MB) is like the processor’s scratchpad — a larger cache, such as the 24 MB in the Lenovo vs. 12 MB in the Acer, helps the CPU access frequently used data faster, making multitasking feel smoother.
RAM and Storage
RAM (Random Access Memory) is your computer’s short-term workspace. More RAM (16GB, 32GB, or 64GB) means you can run more programs at once without slowdowns. Storage is your long-term file cabinet. A solid-state drive (SSD) is much faster than a traditional hard drive for booting up and opening files. Measured in gigabytes (GB) or terabytes (TB), larger capacities let you store more photos, videos, and applications.
