Not sure if this is for me

[DJ Dave]

here is wot am trying to do
i am a computer tech i build and repair a lot of computers for customers
in the past i have used cd’s for all the window installs and in the case of it not having a cd drive or the drive not working i have used usb pens and external cd drives
am now wondering if i can setup a computer or server for network installs
ie a computer setup ready that if some one brings me a computer and it needs xp putting on it i can just hook it up to the network and boot it from the network and choose witch verson of windows to install as i would like to have access to all versons like xp home and pro and media center also windows 7 not too keen on vista
Thanks in advance
