Calm down Dr. Moneybags - look how many RAM chips are on that DIMM... No need to flex your wealth!

IKR? That GPU has a dedicated power connector!

Yeah, that beast can probably host one medium size corporate with Linux, and do some crypto mining on the side

A bit of salty water will do the trick 👍

what, do i dare ask, are the computer holes?

Any Linux that can run a leightweight desktop like Xfce should do it.

At this point, I think the vast majority of performance issues would be caused by the browser itself trying to render overcomplicated javascript-infested pages, not the distro or DE. Pick any distro you want, but use a lightweight browser.

Steaming on a web browser won't work well, but if you can download the file and open it with mpv, or open dev tools and find the stream URL and send it to MPV then it should play fine.

Also I second xfce, any distro will do, I still recommend upgrading to ssd if you can, it's a HUGE performance increase whatever the specks of the machine are.

Try waterfox browser with adblocks. On linux one of the more heavy thing is the desktop manager, so maybe avoid gnome distros, cinammon is also a little bit heavy. If you want to go barebone there are many lightweight distros . Remember that you can run the distro from the bootable usb. Before install anything use the browser and check some video on youtube in full hd or even 4k.
