Ver nice config. Nothing to add really, it's got everything covered.
Have you considered any system imaging software (e.g. Macrium Reflect Free)? Such software allows you to create full backup images of your system to restore your system to its exact state, as it was when you created that system image. So if anything goes wrong you can recover your system from that image instead of doing a clean install from scratch, and the whole process takes about 10-20 minutes.
Thanks for sharing your configuration with us!
