I've used it as a server before and it's quite nice, it just requires getting used to the nix language a bit and possibly dealing with customization work when something you need isn't exposed already in /etc/nixos/configuration.nix. For example, imagine you needed some weird iptables functionality - you might end up writing some shell-ish rules using 'networking.firewall.extraCommands' [https://github.com/NixOS/nixos/blob/master/modules/services/networking/firewall.nix https://github.com/NixOS/nixos/blob/master/modules/services/...]. Of course other admins on your team might have to be on board with this learning curve too.
