I addressed this issue today.

I was concerned about this and did notice that the screws sticking out of the top of the blocks did indeed block one of the PCI slots that I needed.





I spoke with Eddy_EK about this and he suggested that I use sinking screws, as he assured me that drilling out these slots would not affect the block in any way. He recommended ISO 7991 M4x12mm screws.
I found these at the local Lowes:





Something very important to note - Delrin is a VERY soft material for drilling. Without a drill press, the bit WILL catch and you're block will leave the table spinning! See the following hole, which was done with a drill.



As you can see, this hole is too deep for comfort. That's because the bit caught and dug itself deep before I could cut power. However, I leak tested it for 72hrs and had no visible leaks so I threw an o-ring in the hole as a backup and feel confident that no water is making it out.



Because of how soft the delrin is, I did the rest of the holes with the 5/16" bit and a glove. Hand drilling the holes was actually easier then I thought it would be and it allowed me to get a much better hole - so i feel it's the best and safest way to make these sink holes.




The final result is as hoped - with proper clearance being left for the X-Fi card! The motherboard isn't mounted in this picture, so the cards are a bit more leaned then they will be on install - but when held in place correctly, the cards fit almost perfectly. As a precaution, I'm thinking I'll place a few pieces of electrical tape on the bottom contacts of the X-Fi - to prevent a possible short if the screws do touch.



Personally, I hope that Eddy produces these blocks in the future with pre-sunk holes.
