It looks like it has a very limited number of media formats that are supported. A small SBC like a Raspberry Pi Zero 2W or one of the low end Orange Pi boards would be much more useful since there wouldn't be any restrictions on what could be served.
The card is rated for 180 watts. It has a single 8 pin power connector, which means the maximum it could possibly draw is 225W. Pick a power supply that will provide that plus whatever the rest of the computer draws. I would suggest oversizing the power supply a bit so you don't use more than about 75% of it's rated output.
I haven't had any issues with my RX 6700 XT. It works great for games and CAD. I've never gotten the video encoding working though. I think it needs the proprietary drivers.
My newest PC only supports PCIe 3.0. My SSDs are still plenty fast, at least until they start thermal throttling.
When I used dial-up, local calls were free.
I used packet writing for a while when I got my first DVD-RW drive. A few years later, multi gigabyte flash drives became affordable and there was no need to mess with DVD-RWs anymore.
It's an important thing to have in an emergency. The remaining cell towers will probably be overloaded, but you will likely still be able to hear an FM broadcast station to find out if you need to evacuate and where to go.
I don't think a mobile version would be practical, they don't have enough processing power. Blender needs a high end PC.
I picked this little scope up from the Seapac swap meet a week and a half ago for $3. It turns out that all it needed was some contact cleaner to get it working again.
This is a portable scope that can run from 12V DC as well as an internal battery. I don't have the battery for it, but I could probably put some 18650's in there if I disable the built in charger.
You basically need a supercomputer for windows 11 to not run like complete shit. Linux will run well on 15 year old hardware, although I wouldn't suggest anything that old if you care about power consumption.
