Mini PC , AMD A9 9400 (up to 3.2 Ghz) Mini Desktop Computers, 8GB RAM 128GB SSD, Micro Desktop PC with Dual 4K HDMI, 2.4G/5G Dual WiFi Bluetooth 4.0 Type-C USB 3.0 Mini PC

Basically, I bought it to play some older pc games on occasionally. I am not a
"gamer" by any means, and iI intend to keep it off-line for the most part, I have been using different flavors on Linux the past 5 years, which suits my purposes fine. Sometimes you need a Windows pc to run programs that are only available for Windows pc's.

I have now bought 5 of the AMD A9 9400 machines. I am currently using one with 2 monitors to operate led boards and tvs for advertising via a cloud application. And it does a wonderful job. I installed one for a customer to use as a PC at her home. The others are being used as streaming devices, and are performing perfectly. The only problem I had was with audio on one of the hdmi connection. That was remedied and no other problem a reboot couldn't solve. I can totally say I will be buying more of these in the near future. Perfect price for an affordable streaming box with enough processing power to execute smoothly. Beautiful video with audio syncing everytime.

So, after purchasing, I started finding reports of bad updates for Ubuntu hosing the desktop, and different complicated ways to fix it. It all has to do with the R5 video drivers.

Do NOT update the original version of Ubuntu on the mini-PC! Just simply grab a bootable USB or SSD, and install from one of those.

Here’s the important part: DO NOT SELECT 3rd PARTY DRIVERS WHILE IN THE INSTALL. Just install the latest BASIC Ubuntu. What is installled on n the Ubuntu flavor of this machine will choke if you allow an update or upgrade. Just have some kind of boot media ready with the latest kernel,

Here is what to me is the least complicated fix: Go into BIOS by immediately pressing F12 then selecting “setup” after seeing the ATOPNUC splash screen, put in the password, then go to change the boot order. Make sure USB is listed first. Save, boot, install. You may have to reboot a couple times and hit F12 a couple times to get the selectable bootloader, but keep trying.

DEFINITELY fill the RAM to max, and also consider grabbing a larger SSD card for the main drive. Forget about the AMD R5 drivers and just go generic non-3rd party.

As I said in my earlier review that I would add a photo. Well, I have three photos to add. One that shows the whole system - MA90, wireless Logitech K400r keyboard and Logitech M325 mouse, and monitor (29 inches wide), second is view from the rear showing power cable, HDMI cable, Logitech wireless dongle, and Cat5 internet cable third is a view showing 128GB microSD card inserted.

After logging in to my Linux powered AtopNuc MA90, decided I did not want to wait for a 660+ MB upgrade. Had no trouble accessing the device's BIOS where I set it boot from USB using a Logitech K400r keyboard and M325 mouse. Rebooted with LTS Xubuntu 22.04.3 on a USB stick. After installation, everything works like a charm. It works with every monitor I have connected it to. I have experienced no issues with the audio - I used headphones connected to the 3.5mm audio receptacle on the front of the box. I have connected to three other PCs on my network using ssh. It really is a neat little machine. It was a good buy. I will try to add a picture later.
