Oh, and if you are choosing windows for your thin clients, make sure you order the version of the OS that you want. There is no such thing as downgrade rights with HP thin clients and windows OS versions (if you have a way let me know but I spent 4 months dealing with HP sales and support). You can install another version of an OS on your machine but it can't be an HP branded version from an HP image because it will tell you its not licensed for that machine, even if you are windows 8 trying to go to windows 7. You can also install a newer version (ie Windows 8.1) but the management tools didn't work for more than an hour before it would disconnect and never come back. HP couldn't help with that either.
