I noticed there's no picture about the Canopus Pure3D II LX on the "identify your 3dfx hardware" page.
Quickly said, the "LX" version have the same performance as the Pure3D II, except it have no fan pre-installed (but still have the holes and fan connector), and only have the VGA in (Mini-DIN 9-pins) and VGA out (standard VGA 15-pins), no TV out. There are some missing components on the board as well, but they were removed because they are only used by the missing features on the LX card.
Also, this is the reason why i had to make myself a longer SLI cable to plug a standard Voodoo2 to this card, because since i don't have the semi-proprietary pass-thru cable (with the Mini-DIN 9-pin on one side), i can only use it in SLI, and funny enough, peoples who wanted to use 2 x Pure3D II exactly did that: Buying the Normal card, and the LX card for SLI, because it had a lower price point.
Here's a photo of my card:
