Cons
- The included 1TB SSD is PCIe 3.0, despite the M.2 slots supporting PCIe 4.0, which limits initial storage speed.
- Fan noise becomes audible under load, with CPU temperatures reaching up to 93°C in performance mode.
- WiFi 6 performance can lag behind wired Ethernet for heavy data transfers.
- The chassis is constructed primarily from plastic, which some users might find less premium.
- Integrated graphics are not suitable for playing the newest AAA titles at high settings.
Dimension Scores
The AMD Ryzen 5 7640HS with 6 Zen 4 cores and 12 threads, boosting up to 5.0 GHz, offers a 30% performance increase over previous generations.
It supports up to 128GB DDR5 RAM across two SO-DIMM slots and dual M.2 2280 slots for up to 8TB PCIe 4.0 SSD storage.
The fan is quiet during idle use but becomes audible under load, with CPU temperatures reaching up to 93°C in performance mode.
The chassis is primarily plastic, which is decent but not considered premium.
Best For
- Users needing a compact workstation for office tasks and multimedia creation with multiple 4K displays.
- Casual gamers or those focused on emulation up to PS2 era.
- Home server applications requiring dual 2.5GbE LAN and flexible storage expansion.
- Light video editing (4K 60fps with basic cuts and transitions).
Not Recommended For
- Hardcore gamers expecting to run demanding AAA titles at high settings.
- Users who require a completely silent PC under heavy workloads.
- Professionals needing a dedicated GPU for intensive graphics rendering or complex 3D modeling.
Watch Out For
- The included 1TB SSD is PCIe 3.0, not the faster PCIe 4.0 that the M.2 slots support, meaning you'll need to upgrade the SSD to get full PCIe 4.0 speeds.
- CPU temperatures can hit 93°C in performance mode, and one user reported 88-89°C (192F) during gaming, potentially requiring manual fan curve adjustments in BIOS or external cooling.
- The built-in WiFi 6 radio showed slower performance than wired Ethernet for heavy data transfers, so for critical network tasks, use the 2.5GbE LAN ports.
- The plastic construction, while decent, might not feel as premium as metal chassis found on some competitors.

What Buyers Say
This mini PC is a surprisingly capable machine for its size and price, often praised for its snappy performance in everyday tasks and its ability to handle moderate gaming. Users frequently highlight the ease of upgrading RAM and storage, and the extensive port selection, especially the USB4 and dual 2.5GbE LAN. However, some have noted that the included SSD isn't the fastest PCIe 4.0, and fan noise can be noticeable under heavy load, with CPU temperatures climbing. The plastic build is functional but won't win any awards for aesthetics.
“Dude, this little box rips for the price, I can actually play some games on it and it doesn't choke when I've got like twenty tabs open, but that fan gets loud when it's really working, and I wish the SSD was faster out of the box.”

Buying Guide
When you're looking at mini PCs like this, you're basically trading raw power and extreme upgradeability for a tiny footprint and lower power consumption. You need to decide if the convenience of a small box that disappears behind your monitor is worth not having a massive graphics card. Think about what you'll actually do with it daily – browsing, office work, streaming, or some light gaming. This isn't a gaming console, but it's way more than just a web browser.
Processor (Ryzen 5 7640HS)
This is the brain of your mini PC. The Ryzen 5 7640HS is a modern chip with 6 cores and 12 threads, meaning it's really good at handling multiple tasks at once, like having a bunch of browser tabs open while editing a document or streaming video. It's like having a fast, efficient engine in a small car.
RAM (32GB DDR5)
Think of RAM as your computer's short-term memory or workspace. 32GB of fast DDR5 RAM means you can have a ton of applications open, switch between them quickly, and handle memory-intensive tasks like photo editing or running virtual machines without slowdowns. It's like having a huge desk to spread out all your work.
Storage (1TB PCIe SSD)
This is where all your files, programs, and the operating system live. A 1TB PCIe SSD is much faster than older hard drives, so your PC boots up in seconds and programs launch almost instantly. It's like having a super-fast filing cabinet for all your digital stuff. The fact that the slots support PCIe 4.0 means you can upgrade to even faster drives later.
Integrated GPU (Radeon 760M)
This handles all the visuals on your screen. Since it's integrated, it shares memory with the main RAM. The Radeon 760M is capable enough for smooth 4K video playback, running multiple displays, and even some lighter games at decent frame rates. It's not a dedicated gaming card, but it's more than enough for everyday graphics and casual fun.
Alternatives
If this mini PC doesn't quite fit, look for models with a dedicated graphics card for serious gaming or professional rendering, or consider barebones options if you want to choose your own RAM and storage for maximum customization.
