Review: mini pc for 2 months - After two month this mini pc just died. Almost 700 euros and not working after 2 months! Avoid! EDIT: Nice people from Minisforum send me replacement and now everything working just perfectly, as it should. I change my review to 5 star now, this mini PC is real beast in small package.
Review: A compact and powerful desktop PC with only minor issues. - I bought the 32Gb 1Tb model. First and formost! It come with Windows 11 Pro, not sure the barebones model has a licence. Noise Level: I only use it for software development purposes and it is silent! Aesthetics: Looks a bit cheap due to plastic chassis. Although it feels weighty due to the large heatsink which helps to keep it quiet. Memory: Adata 32GB 5600Mhz CAS: 46 Hard Drive: Kingston OM8PGP41024Q-A0 3700/2600 (mid-range Gen 3 speeds) Wifi Performance: This is the weak part of the system. I am lucky and have a mesh access point within 5 metres of the device. However when I switch that off and use the main access point which is 2 walls and 10 metres away then the signal is dire! Minisforum really need to include an external antenna for the wifi. Bluetooth: Keyboard and Speakers connected without issue Performance: Very responsive, cannot fault it so far, it is very snappy, no delays in opening apps. appears to work as well as my 7900X desktop.

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.
Good afternoon,You can see how to c disassemble (replace RAM and SSD) by following link

### ⭐⭐⭐⭐ A laptop in a box.
*by R***R on 17 February 2025*

The build is a low-end laptop in a small desktop case. The system's feature set is designed to provide a cheaper option to Miniforum's higher-cost UM890, but as long as you do not need the extra expansion found in the UM890 this unit will provide a good system. Things to note - To get inside you have to remove the 4 stuck on feet, but only 2 replacements are included in the package. - The device can be powered via the USB 4 port, but the performance is greatly reduced to what you can get out of the device with the supplied power supply. - It shipped with a Win 11 Pro licence. - If you plan to leave it running in a bedroom you will need to tape over the on-off switch, when turned on its state is indicated with a very strong blue light.
