does this card include the fullsize atx bracket or just low profile?

The card I bought had both the short and tall brackets. I had to install the tall bracket for my system. Requires you to remove the 2 nuts for DVI connector.

will this work in my 32 bit Dell Workstation?

Jim...the Quadro K420 is working perfectly. Thanks for revealing the mystery behind the self-installation disk and the wrong driver it automatically installed.
