Added temporary notes on remote building, and modified hardware configuration to be specific to system for steamdeck, changing steamdeck.nix to its user specific config. Possibly pending modifications to configuration.nix under steamdeck.

+Yes, that's a good approach! You can test the build without actually applying it in a few ways:
+
+1. Build without applying using `nixos-rebuild`:
+
+```bash
+# Build only, don't switch
+nixos-rebuild build --flake .#steamdeck
+
+# Build for a remote system
+nixos-rebuild build --flake .#steamdeck --target-host root@remote-ip
+```
+
+2. Check evaluation:
+```bash
+# Check if the configuration evaluates without building
+nix flake check
+
+# More detailed evaluation
+nix eval .#nixosConfigurations.steamdeck.config.system.build.toplevel
+```
+
+Since there's no sensitive data yet, it's a good time to test the basic structure. Secret management can be added later when needed.
+
+Would you like help setting up the remote build testing? We would need to:
+1. Ensure SSH access to the remote machine
+2. Configure the remote builder
+3. Set up necessary permissions/access
+
+Also, there's a feature in nixos-rebuild called `--build-host` that could be useful - it lets you build on a more powerful machine while targeting another system.
+
+Would you like me to provide the specific commands and configurations for any of these testing approaches?
