thanks for posting this package.
I tested these drivers on a dell optiplex 330 and they worked great. Win7 is not supported on the Optiplex 330 according to the website but win7 works just fine.
In case anyone is interested, I used audio, chipset, network, storage and video.. I removed the extra from network/video that dont apply to our model and it was about 100MB only and all drivers were installed wit no problems..
