XFCE or LxQT but i have a preference for XFCE if it is for normal use.

honestly they are all pretty good at this point. start with the default ur distro supports. if that isn't to your taste try kde/plasma, gnome or lxde

In my experiments with a similar setup and integrated graphics, full-wayland Kubuntu feels much more responsive than Xorg-Lubuntu, for what it's worth

river or sway

I recently bought netbook on AMD c50 for 20$ and firstly, i bought some ram and ssd, luckily ddr3 is very cheap, one or two 8gb sodimm modules and 256gb ssd, or in my case 360gb because price was the same when i ordered them, 360gb was even slightly cheaper, so what i was trying to say, this small cheap upgrade will make a world of difference, and when they'll arrive I'm planning to install "tumbleweed kde" , whole cost of upgrade is 8$ for one module of 8gb ddr3 sodimm, and 17$ for 360gb ssd, 256gb price was the same as i said before

Moksha Heck, just install Bodhi Linux 7, your choice between Ubuntu based or Debian based.

Ironically, ChromeOS Flex would run smooth on those specs, since it does so on my dogshit Samsung Chromebook 3 with shittier specs.

If the PC has an SSD, install anything you want, the PC will handle it fine.
