Good specs for basic needs. Machine is quiet. Wiping out Windows and installing Linux goes without any issue (see below about WiFi). (Specs are: UM870 with Ryzen 7 8745H, 32 RAM, 1Tb SSD)Besides different positive reviews on the gaming part there are some noticeable issues with this machine, and giving just 3 stars.1) It has Windows installed, should be optional.2) All USB ports are flipped upside down (i.e. if you pull an USB stick from your other computer or laptop, you need to rotate it 180 degrees to insert).3) There is no USB-c port at front, this is very inconvenient. Indeed the other one is on the back, potentially used to connect a monitor.4) Using WiFi module (Mediatek 7902) that is not supported on Linux. Usually that is not a problem at all, someone would rather use a wired connection because any WiFi is not fast enough for today's Internet speeds. Indeed, didn't even check this before discovering other review about the same problem.

This little box is powerful! Best purchase I've made in a long time! Came with SATA cable and several others! Blazing fast. Lots of ports and room for a 2.5 inch second drive. It is literally a 5 minute job. Easy peasy access to the guts of this machine. Incredible little machine had windows 11 pre-installed. Running two monitors and one is 4K- BEAUTIFUL. I might have preferred two HDMI ports instead but thankfully MINISFORUM included a C connection! This company thought of everything and the price can't be beat. I'm a graphic artist and I'm running a large tablet with zero issues. Plenty of power. Smooth installs and this unit is cool and quiet.

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.

First off, I did upgrade this thing to the max, 94Gb of DDR5 5600MHz RAM, and dual M.2 NVME drives. You have to go into the BIOS as set a dedicated portion of the RAM for use as video RAM (can be up to 16GB) and since it does not have an hard drive and OS then you will need the driver package from the MinisForum website. The model UM870 slim uses the same drivers as another model (like UM640 or something) but they work fine.This runs games faster and in better quality than my PS5 does. I definitely recommend it. And it was about the same price to buy this bare bones system and then get twice the RAM and hard drive size on my own than even the largest amount offered on a pre-built bundle. Not including an OS, but I already have a Windows 11 Pro key, so I didn't have to include that in the cost of building it on my own.The 4 stars out of 5 is just because of the way the bottom of the system is. First off, it is a bare bones system, meaning you absolutely have to open it to put in RAM and a M.2 drive (or 2) yet in order to open it up you have to pull off the 4 rubber feet that are held on by sticky tape, and it only comes with 2 replacement feet (by the way, you also have to remove the feet if you plan on using the vesa mounting bracket or you need to supply your own longer screws). Then you need to remove 4 screws that use thread locker on them, then you can pop off the bottom cover, and be careful not to pull it off too fast, because the cooling fan is screwed to the bottom, and attached to the motherboard with a 4 pin connector. Also, the cooling fan mount is just a thin sheet of metal and comes with 2 thermal pads on it so it is supposed to act like a heat sync for the 2 NVME drive slots, but does not allow you to put any 3rd party heat sync on the drives because there is no room for the cover to go back on. However I was able to modify the fan mount by basically cutting 90% of it off and moving the fan over so it is only held on by 2 of the 3 tiny screws that hold the fan to the bracket, and only 2 of the 4 screws that normally hold the bracket on, and having to cut a small notch out of the inside of the bottom cover. Basically they could have made it fit, and allowed for better heat syncs on the drives, but decided that one flat piece of steel would be better than aluminum finned heat syncs.Would have been 5 stars if the had just left the feet off and included them as an optional add-on in the box. Had not used that blue thread locker on 4 screws that 100% need to be removed by the customer, and had just moved the bottom cooling fan over far enough to allow for better 3rd party heat sync options to be used (without needing modifications).Also, I don't need the dual Ethernet ports, and would have much rather it had an extra USB-C port. But I just used one of those USB-C hubs to add a bunch of extra ports to it.
