Alienware Aurora R3 - how to open case (How to remove (open ) this plastic cover ?)

I have pulsing noise coming from this area. probably from cooler, want to fix it...  :(

This isn't the R3 Aurora but the cover removal is probably similiar. The cover removal is shown at about the 40 sec mark. The HD fan removal is shown later in the video. I won't be getting my Aurora R3 for a few more weeks so I have no way to check the accuracy yet.

Probably i was wrong. It's not cooler. It's HDD making this pulsing/buzzing noise ..... Any idea how to fix it ? ( probably not ... )

Thank you. It's helps.

Did you ever figure this out? We just got a new Alienware Aurora and also have this really annoying pulsing sound that doesn't stop. I have never heard a computer this loud before! It's really annoying and if I had known in advance that this would be so noisy, I would not have gotten it.

Mine ( Area 51 ) did this and the fix was to replace the PCI fan. Cost me $30.00 from newegg.  If you are 100% sure it's the HDD and it's not NORMAL HDD sounds then it is time to replace it before it fails.
