Very nice and to answer the question about Arch Linux. I've been a long time Arch user but I was needing to install on my laptop and I thought I would give ArchBang a try (Arch Linux with Openbox Window Manager) already setup I just as you said and did sudo pacman -S gnome gnome-extra to install gnome check my screenshot out [link] It's running like a dream.
Thanks! Gnome-Shell theme is: GNOME Shell - Elementary Luna by half-left: [link] Icon theme is my mix. All of them you can find in my Favourites. Just replace icons in theme with icons you like: [link]
If you want gnome, then type this: sudo pacman -S gnome gnome-extra There's a lot of things you need to know before installing Arch Linux. Take a look at Official Installation Guide and Beginners' Guide on Arch Linux Wiki: [link] [link]
