    Great little PC!

    Really happy with this mini PC! It's much smaller than I expected but surprisingly fast. It starts up in seconds, runs multiple apps without slowing down, and stays nice and quiet. I've been using it for work, streaming videos, and everyday browsing, and it handles everything with no issues. The setup was quick and easy, and it doesn't take up much space on my desk, which is a huge plus. For the price, the performance is excellent. I would definitely buy it again and recommend it to anyone looking for a compact but capable desktop.

    Great apple mini pc alternative — Excellent Value

    Bought this as a gift for my colleague's son, and he loves it. I wanted something comparable to the Apple Mac Mini but cheaper, the same solid performance. He uses it for homework, coding, streaming, and even light gaming, and it handles everything smoothly with no lag. Compact, fast, and great build quality for the price. Highly recommend!

    good product and bestbuy service

    I have to comment on the good delivery service from bestbuy Because of autofill address, it mixed up office and home. But they called and solved on site which provided the convenience. For product, it balances of CPU power, graphics capability, and expandability for other functions, its a great product though the RAM/SSD pushed the price higher than otherwise. Its still a good choice in the market.

    Excellent Little Machine

    I'm running Linux on the UM870 Slim as a dedicated development machine, and it has been excellent. The Ryzen 7 8745H is fast, builds are quick, and it handles development tools, containers, and multitasking without a problem. Linux runs great on the hardware, and the machine is quiet, compact, and uses much less power than a traditional workstation. I also like that I can upgrade the RAM and storage as my needs grow. Overall, it's a powerful little Linux development box and a great value for the size.

    Mini computer

    It’s super fast and works like a regular computer. I use it for school, work, and video gaming with no problems. My only regret is that I wish I would have bought a version with more storage.
