actually if you do have drivers for your hardware,using vLite and removing the in-built drivers from vista,can actually save you a lot of HDD space.Removing all the unnecessary modules,languages and stuff brings down the actual install disk size to around 680 MB.
All you will save is 1.5GB harddisk space, but here is the thing. First go & find out all the drivers for your computer, if you do find them then it is very good to slipstream them only & remove the rest of the drivers.
However, removing the inbuilt drivers of Windows takes away most of the Plug n Play part. It is better to keep them the way they are. If you want delete them after installing Windows.
