UM870 Slim Mini PC Barebone AMD Ryzen 7 8745H(8C/16T), Mini Desktop Computer Without RAM/SSD/OS, AMD Radeon 780M Graphics, USB4/HDMI2.1/DP1.4 Output, 2.5G LAN, 4xUSB Ports, WiFi 6E, BT5.3

Being an avid pc gamer who has to spend a few nights a month out of town for work, I wanted something powerful with a small footprint. I thought about a Steam Deck or a Rog Ally X, but came to the conclusion that id basically only be using it Docked mode, so the built in screen and controller would not be used, therefore not worth the added cost. Started researching and landed on this. The processor is great, the size is mind-blowing, and the 780m packs a punch for graphics. Gaming wise, here's the brutal truth- Steam AAA games with FSR still look pretty good, I spend most my time gaming on an RTX 4080, so definitely had to temper my ecpectations- knowing that, very happy with the performance. Being able to play newer games on the road is wild. Especially for something that fits on the palm of your hand and weighs about as much as an Xbox controller. Putting together was a snap, I actually did the entire thing in a hotel room with a screwdriver on my keychain. disregard the reviews about the feet needing to be pryed off- as of July 2025, the units no longer have the feet preattached to the barebone kit. Heres where this really shines, emulation gaming. Expect 1440p 60hz on PS3, Wii, Xbox 360 Expect 1080p 60hz on Switch Expect 4k 60hz on everything below (would be an infinite amount of FPS, but there are limits non related to this actual equipment). Bought a cheap case and have my whole setup to take literally anywhere now. 10/10, would buy again and again

This PC is pretty awesome. I am using it as a Kubernetes node, and it performs spectacularly. My only big complaint was that in order to take the case apart to install an SSD/RAM, you have to remove the feet on the bottom of the device. The feet are adhered to it with some form of adhesive and that adhesive will wear out over time, preventing the feet from ever sticking again. They only included 2 replacement feet in the box but you need to remove all 4 to take apart the case.

This thing has plenty of power, room for memory and ram to function quite well as an efficient home server. I'm not a gamer and I guess people do play some games on this thing - but I basically have my own internet hosted at home. This box has my photo collection, files and documents, manages my passwords, I can share files from it, It's amazing. It has enough usb ports including usb 4.0. Speedy memory, (DDR5), supports up to 96gbs and up to 8tb of storage. I will probably by another minisforum in the future.

The only bad things I can say about it is the process to open it involves removing the feet which are stuck on and the stickiness will wear overtime if it's open to often. You then need to use a tool to undo the clips to remove the cover. Other mini PCs I've used just have exposed screws on the bottom and the panel is then free after they are removed. The fan noticeable at idle, and through under load it doesn't get much worse. The Good. Amazing performance at an extremely low power draw. Dual m.2 2280 NVME slots and pads are included so you can cool them. Note that you need bare NVME drives, ones with a case won't work as you won't be able to close the lid. Triple monitor output, I did run into issues where none of the Display Port to HDMI adapters or cables I had worked. However, a DP cable to a DP port on the monitor did work. I ended up getting a new DP1.4 to HDMI adapter which is labelled as "8K" and that adapter is recognized and works. It won't break any records versus a PC with a discrete GPU for gaming. But the specs match up to the Z1 Extreme and Z2 found in current handheld gaming PCs. But this has higher TDP, so it'll can hit more performance. You just don't be running them at 4K, but if the Steam Deck can run it, this will as well at better settings.

The computer is nice, runs everything great! The only complaint I have is if I waited about 2 weeks more I could have saved $35.20.

Bought for my 6 year old to play ABC mouse, Fortnite and Jurrasic world evolution. Runs these games shockingly well. I overclocked to 3000 mhz at 80 watt TDP on the igpu and it's cranking out around 80-90 fps in fortnite at 1080p.

It worked really well for about 3 months, then it started to act up. Initially the ethernet device just vanished. I had to reset the BIOS and reinstall the driver then it reappeared. Then it started crashing on waking from sleep. The diagnostics always came back fine but there was no way to avoid crashing after sleep. I switched to hibernate. Then finally Windows 11 began giving errors. I tried to reinstall Win 11 and that's when error after error came during the installation. Basically, I could not reinstall Windows. After 2 days of attempting to reinstall Windows, I gave up. It's a low quality product and I would not buy. It looked really practical at the beginning but after 4 months, it is evidently an unreliable product.

Plastics are very flimsy. If you swap RAM and storage around more than a couple of times, I wouldn't get this or any other plastic mini PC, as the stand-offs for the screws that hold the bottom cover of the case are maybe only glued in, so they separate from the top of the case. Form factor is good, cooling is great, and performance very good as expected. The Wifi card that ships with it doesn't support many mainstream Linux-based distributions even with 6.x kernels. I swapped the wiresless nic for an intel chipset based one and its excellent.
