The default configuration.nix created by the NixOS installer[0] is a KDE environment already, and it's relatively simple to expand and iterate your system configuration (no restart required!). Personally for me the hardest part was figuring out partitioning (since I rarely do that), but YMMV. Hope you try it sometime!

Yeah, I would love to see a repo with more example configs, for example "This one looks like Ubuntu, this one is more XFCE focused, here's a tiling wm one." and so on.
