Well, the riser cards always generate the problems of card fixing in the computer's chassis.

These combinatons of risers and cards ( witch reminds me from the bremen musicians story )are always higher, and cannot be fixed anymore when a riser is used.

Of course, for Half Height Card there is no problem, but all the voodoo cards are Full Height Card.

Most of the people including me are using different improvisation, like fixing or holding with a wire, using a box as support and so on.

I come today accros to a very good ideea witch i want to share with you.



It's recommend a #6 (M3.5) 1.5 inch (40mm) or  1.75 inch long machine screw that threads into the card hold down hole in your computer's chassis.
Also is suggested to putt a nut threaded midway along the screw.
This allows you to screw down the adapter and the card firmly into the chassis.
Adjust the nut (s) so that the PCI card is inserted straight into the adapter.

The ideea is suitable for the following combinations:

voodoo4 4500 AGP + AGP2PCI riser
voodoo5 5500 AGP + AGP2PCI riser
voodoo5 6000 AGP + AGP2PCI riser
voodoo4 4500 PCI ( no DVI )+ PCI2PCIE riser
voodoo5 5500 PCI ( no DVI )+ PCI2PCIE riser

TO DO

For these combinations:
voodoo4 4500 PCI ( DVI )+ PCI2PCIE riser
voodoo5 5500 PCI ( DVI )+ PCI2PCIE riser

i have no suggestion, i have myself the problem in my PC.
The problem is that in this situation the DVI connector hit the nut position, therefore the DVI is not accesible in this case and you must use only the DSUB output.

And, as final word, the bigger the case is, the better you can install the card + riser. I recomend E-ATX cases - server cases.
( Running the PC with the open side panel is not safe )
