I love the minimalism of stock Gnome. You don’t have to make those Ubuntu icons as small as possible or auto-hide the dock. You don’t have to go to obscure settings windows to hide icons on your desktop. It’s just minimal out of the box. Just you and your apps. You can have floaty windows if you want, but it’s also really simple to run your apps fullscreen or half-screen with just a keystroke. I love it.
I got a 12U roadcase rack at Guitar Center last year. It’s nice but it’s only 17in deep which means my choices for server chassis were pretty limited and I haven’t been able to find any rack rails that fit.
