Yes, I emailed them. They sent me a link to the 1 set of clips they sell with the message that they were the wrong size for my motherboard. They did not know of another source to obtain them.
Say, did you ever find the parts you were looking for? I have a customer who sprayed oil into the case to get the fans going. The oil ate away at the plastic pieces and one broke.
If you did, please let me know where I can get some replacement parts.
