Hiya Hardrocky.
Thanks for your reply !
10 out of 10 score for you for understanding the actual problem.
10 out of 10 score also for guessing what I had already done as a temporary workaround
!
I used some of the rubber washers that are included for horizontal mount however because I want to minimize risk of damage to the thermal tape for the moment.
It would be decent though (and much appreciated as well) for Antec to acknowledge the oversight and help me find a proper solution dont you think ? I'm not trying to be difficult bu I was hoping for some better alternative solution(s) in which the harddrive sits flat against the chassis as opposed to on top of some washer. This because I don't want to create some possible cause for vibrations.
I have considered drilling the holes bigger but firstly that would void warranty and secondly it looks like there may not be enough clearance to make that work (+ harddisk touching the side again could cause/transfer vibration).
Admittedly I am somewhat shocked about the fact that this can happen (all my harddrives are the same dimensions so a quick check at design time should have easily uncovered this).
Also I am a bit disappointed how long it is taking to get any feedback from Antec tech. support.
The response to this topic is the only thing substantial I got.
Other than this little issue though the record should reflect that I really like this case. It was exactly what I needed. Quiet, compact as can be but still (theoretically ;o) ) allowing me to mount several harddrives and an optical.
