Review: Small and brilliant.. - Firstly, let me say that I had to return this PC because there was something wrong with it and I didn’t have time to mess about and fix it. It was a WiFi issue that needed more time to be solved but sadly at this time, I just didn’t have it. I will be buying another one in a couple of months when I have more time. I connected the PC by network cable eventually (trailing across the floor so not ideal) but it was an absolute blast while it was working. My PC at home for the past year has been a Mac Mini M2 and this thing was easily as fast as that. I work with Adobe software (CC) and after I installed the suite on the Minisforum, and it did all its windows updates, it was just as fast as the Mac Mini, maybe a little faster. Apps seemed to launch quicker and run a little more smoothly and it had no issue running my BenQ 4K monitor. Colours were accurate and the display scaling worked a treat. My Mac makes a mess of running at 4K - the menus are tiny and there’s no way to change that other than dropping the resolution on the monitor - thanks a lot Apple. Who’s going to purchase a 4K monitor and be forced to drop it to 1440p to get it to work? This PC was very quiet and has plenty of connection options compared to my Mac. It’s also under 50% of the size of the Mac Mini and this makes it very unobtrusive. There are no vibrations or strange noises coming from it and the SSD is very fast (as fast as the Mac) so no issues there. There’s plenty of RAM (32gb) so I never experienced any issues running PS, Illustrator, Bridge, Edge and Outlook at the same time and using large files - most of the artwork I work with is 100mb + and it never missed a beat. I can honestly say that it exceeded my expectations and I will be purchasing another one to replace my Mac Mini in a couple of months when I can iron out any issues that may arise. Finally, I have to say that I contacted Minisforum for support and they were polite and very helpful - again not what I expected at all!
Review: Brilliant, quiet, really fast and good value - My first mini PC and it's brilliant. In some ways it's made my bigger, noisy gaming desktop PC redundant. Firstly it's really quiet, great for office work. It's efficient in wattage making it cheap to run for 8 hours a day. You can throw any app at it and it'll handle it. Around 10w idle, and 65w during gaming. It's not a gaming PC, but it can play games and play very well. Check out the YouTube videos. For reference I've tried it with CS2 (100fps) Witcher3(50fps dx11) Helldivers2 (40fps) no problems, on 1080p on low/medium settings. And can go even higher if you turn on quality scaling. Can support 3 monitors at the same time. Overall brilliant, fast, energy efficient, quiet and tiny :)

**Q: I'm wondering if the EM680 is smaller than a regular mini pc, and does that CPU performance suffer?**
A: Dear customer，

**Q: Does the hx99g support 120hz or 144hz through hdmi at 1080p? i see that it's 60hz at 4k but i would assume something for gaming could output more.**
A: I think that’s the limitation of this computer. 60hz @4K. If you need to look for more then this is not the desktop for you.

**Q: Can additional ssd be added by just removing the top cover? Also, would this void the warranty?**
A: Dear Friend.

### ⭐⭐⭐⭐⭐ My experience with this little PC so far..
*by C***N on 1 September 2025*

A proper mini PC that didn't cost a fortune. For around £270 it's got a Ryzen 7000 CPU and surprisingly, dual PCIe Gen 4 NVMe slots. That's a huge deal at this price and makes it easy to upgrade the storage later. The connectivity is solid too, with a nunch of USB (including USB4 port!!!) and 2.5G ethernet. The USB4 is the real party trick here, this lets you hook up an external graphics (eGPU) for some gaming with recent ‘AAA’ titles, which my be perfect way to scale up in the future, if this PC is your long-term investment. The only drawback for anyone into upgrading is that the RAM is soldered, so it can't be swapped out later. Its not an issue for me since I didn't plan on upgrading it anyway, but it's good to know. All in all, it's a brilliant and solid piece of kit for daily work and even some light gaming, including emulation. This little box proves you don't have to compromise on features just because you're on a budget. Recommended.
