Okay so I've been lurking around /g/ for some time now, specifically on desktop threads. But since I am too dumb to linux idk how they do it. What I want to know is how to make my Arch Linux installation look like this?
It actually says that too. The distro is Arch Linux, the Window Manager (WM) used is OpenBox (install this using pacman, your distro's package manager) and apparently that supports theming as well. Install OpenBox with the cuteasmysoul theme and take it from there.
...for the date and time you may also need to set your system's regional preferences to Japanese so you get the full weeaboo experience, but don't come crying to me if you can't use it anymore.
There is no 'actual' desktop environment in the case of that picture. What there IS is a standalone window manager. In this case, it's Openbox. And Openbox is on its own.
So, to sum it up, no. no MATE. Only Openbox which has been customized.
Bah! Stop mollycoddling the youngster. I did a Linux From Scratch on my Pentium back when they didn't have virtual machines. I had to reboot if I wanted to go back to Windows.
Now excuse me, I have to go comb the tangles out of my beard.
