A few people asked me how well PCIe x1 cards fit in the x1 slot on BloodRage above the first x16 slot.
The NB is close and one of the screws holding it seems to be in place if your using long cards.

But thats actually not the case. The screw is short enough to allow even full length PCIe x1 cards to fit.
It doesnt matter if you use the Heatsink or bundled WaterBlock, theres enough space for the cards

So any x1 card will fit, whether its Creative XiFi, Xonar, NIC, Raid or TV cards etc, as long as they comply with the PCIe spec they will all fit
