Its a program called neofetch that you can install through your distributions package manager. Then when its installed, you just type neofetch into your terminal and it will generate that info for you.
InstantOS has an interesting window manager and a cool installation process, walks you through choosing various options. I like it, as it saves you some time being already pre-configured. But for some reason, I cant get used to Window Managers yet, maybe in a few more months it will be more appealing. I think if you want something nice looking out of the box with a window manager, this does seem like an interesting option.
I use a PopOS/Gnome and a Gnome extension for window managing - GTile.
I've worked out these ONE handed shortcuts, and now I can't live without it. I even had to find the equivalent for Mac (Magnet).
Super+Alt (with thumb) + Key to make the window snap with 1 other finger.
Q,A (top and bottom of screen), Z,X (left and right of screen)
W,E,S,D (4 corners of screen)
1,2,3 (3 columns, 3 thirds of the screen)
4,R (2/3rd Left and Right)
F (Fill screen)
V (Full screen on/off)
(I applied the same shortcuts for my Mac. Had to pay for the app but quickest purchase ever.)
PopOS's shell auto-tiling is neat, but it doesn't give me the control I want. Or maybe I haven't gotten used to it. They do have shortcuts for juggling the windows around (like swapping windows etc). But I just prefer my way.
