360 video editing and davinci resolve
This was purchased (4 months ago) for editing insta360 x2 and gopro Max (360 cams) videos of dual sport and dirt bike rides. We use davinci resolve (finalizing flat video) , gopro player (reframing 360) and insta360 desktop (also reframing 360) for all of the simple ride videos that we do. The speed of the 6800 is fine for our purposes, and the onboard graphics can handle the simple editing also. Most of the files start out as 5.7k 360, then reframed to 1440p (flat) video, and finally exported from DR18 as 1440p. During editing / reframing there are rarely any lags at all, if you wait until the caches are completed after importing. Normally I'll use 100Mb/s for exporting, and h265. I did open this unit to install a total of 32gb of ram, and that seems to be enough for these editing needs. The only complaint is that w11 is wonky sometimes, when dealing with the weirdness of "please use edge instead of chrome!" after a software update. This can't be attributed to the hardware though, I completely blame w11 for this weirdness. A restart (or another lol!) after a software update usually fixes that weirdness. I've looked at the external docks for dedicated gpu's, but so far this minisforum has been plenty for simple 360 5k video editing. I do not game at all. The bluetooth and wifi has been rock solid. You'll want to make sure and get a kb/mouse that has a wifi/bt dongle , if you plan to be completely wireless and want to change bios settings occasionally, as this unit does not have bt turned on during bios settings... so just switch the kb/mouse to whichever mode your plugged in dongle supports. Fan- almost zero noise. Memory- it's a good idea to get the 32gb option, or just add it cpu speed- good enough for 360 5.7k video editing htpc- we use it for 4k/8k youtube entertainment, it works fine for this at 60fps 4k and 24fps 8k. lags- haven't noticed any. weird restarts- zero bugs- none noticed, yet annoyances- maybe put a piece of tape over the power on led. it's blue, it's bright the only reason for 4 stars instead of 5 is it would have been nice to get the 32gb version for the same price. Maybe i'm being too picky on that. I may update that later to 5.

Fast but....
Unit is fast, but lacks WIFI, and while supporting a 2nd NMVe drive, lacks a SATA drive interface. And only 1 stick of 16mb of memory is include, although there is a second space for another stick: mixed bag here...
