I use Haiku in my old Asus EEE PC 701. It fits in the 4gb SSD leaving space for applications, 1gb of RAM is enough and it supports a lot of daily use applications like libre office or emacs(I'm using version 29 with denote for my personal Knowledge Base). The only think that I didn't manage to make work was the camera. It's very stable on that machine and gave it a new life making it pretty usable, even for browsing the web for content(not heavy social media sites). YouTube is possible with low resolution through other applications, not the browser.
