Top Shelf Mac Pro 1,1 removal

[IcedOut]

So I got this Dirty Mac Pro Case and want to mod it but I struggle to remove the top shelf in the case. I saw some other threads but I couldn’t figure it out anyways. I removed all Screws, I struggle to remove the Clips from the locking mechanism and I don’t know if there is anything else that needs to get out before I can remove the top shelf. Please help meee

By the way, Pictures or Videos would be helpful or a German explanation

I ended up cracking my locking bar removing that shelf replaced with magnets lol
