At work, we use SCCM to do this. You just plug the PC on the network, PXE boot, and it does its thing. You can also create a USB drive installs the same image.

At work, we use SCCM to do this. You just plug the PC on the network, PXE boot, and it does its thing. You can also create a USB drive installs the same image. It then proceeds to install the third-party software via SCCM, too, so you don't need to upgrade the installation image every time a new app version is released. One caveat is that SCCM is not free, and we have a dedicated guy managing it. Not sure how much work that entails (he's not full-time), I rarely if ever touch our Windows environment (I'm running Linux on my own machine).
