I had an issue somewhat like this... I was putting some equipment into the case, and when I was done, I couldn't find one of the little plastic pieces that allows the front panel to be installed. I did the Lian Li service thing, but their entire system has messed up errors--I either get an error upon posted the message, or I get a blank e-mail after.
Luckily, I posted about it on here, and Zepper posted a link of where the part could be ordered... So it should be in the mail or something to that effect as of now.
I bought the case from Performance PCs, and they have been exceptionally helpful thus far, as they are trying to locate the part for me as well.
In regards to cases, I don't think I will be getting or recommending Lian Li again... Enermax & CoolerMaster are still on my good list though.
EDIT:
Here's the website that has Lian Li case stuff. You might want to see if they have your exact fan and everything, if you want an exact replacement...
