waste of $370
Size: 16GB+512GB I 7640HS
caught this mini pc on sale for $370. so far so good, i’ve played many games, sims 4 (modded), all the grand theft autos, south of midnight & a few others no issues. i’m only giving 4 stars because i don’t have enough storage alone. i did already have an external hard drive but i thought it came with more storage space. it may be because of my sims mods. Sometimes it does get loud with the cooling fan but it doesn’t last long. for the price i got it im pleasantly pleased. ::::::UPDATE:::::: this thing is an expensive pos, it crashed in the middle of me playing the new 007, screen started glitching, i was told to reinstall windows & it won’t read my USB. then when i get it to read the USB it says it doesn’t have the drivers needed to set it up. I’ve ran into every issue. right now it only loads into BIOS. I reached out to customer service they say it’s a bad SSD. & I have to remove the SSD and send it to them on my own dime. I requested an entirely new system since i’m under warranty, they declined.

No Suppoprt for Dead fan...
We are a software engineering company . We don't do anything on this device except write code. We purchased this mini-pc to give one of our employees more options for the kind of monitor they use. We have been using (4) DELL AIO PC's for over 5 years, all without issue. We tried BEELINK first with very poor results, system was unstable,fan rattled constantly and was unable to successfully talk to Silicon Graphics USB converter chips. Returned to Amazon. Thank you Amazon. The GMKtec has been flawless, stable, quiet, cool (thermal) and capable of any USB task we need performed. The GMKtec runs 16 hours a day, 7 days a week tied to a DELL 27" monitor. We also added a 1TB high-endurance m.2 SSD... GMKtec is excellent in every way. UPDATE: After 5 email they refuse to even respond about replacing the primary fan that died. Lasted 8 months, now its just a brick...

Unreliable defective
Size: 16GB+512GB I 7640HS
About a dozen times this unit loses the internet connection then crashes to a green screen. Brand new install with hardly anything running. Seems to be defective. Cannot even install new graphics drivers because it crashes during installation.

Fried itself wile updating
Size: 16GB+1TB I 6650H
Wile asleep watching a YouTube video. It updated and fried itself. This is on night one of owning. Do not purchase. Build a pc or get a laptop. These things are cheaply made.

bought two and both crashed and could not be salvaged
Size: 16GB+1TB I 6650H
I bought 2 of these computers and both computers crashed during Windowns updates. I also could not installl the printer drivers and my legacy apps. My IT guy from Caltech went thru these computers including booting up from bios and said the engineering and parts are absolutely terrible and memory is soldered so cannot be replace. He advised me to never buy from this brand.

Not worthy
If you need workstation, then stay out of this brand. All cheap quality components. A core i9 CPU benchmark score is only 3415!!!! But it should be around 10k-16k. Then whenever I tried to run my VMware it act like a dual core processor may be core i3 or lower. Only thing is good I can say is the outer case.
