Video card holder / support

[otogrim]

Ok I'm planning on buying a friend of mines danger den nv-78. While he had it in his rig it made the card bend a little so I'm guessing it's pretty heavy. My question is, is there any way to support the card. I've seen one that attatches to the card and keeps it in place but i can't quite remember the name of it. If anyone could point me to the right direction it would be greatly appreciate. Thanks
