Hello -
I have a Vega 100G with a bad fan. I’d like to replace it but I can’t seem to figure out how to get the dang thing open. It’s no longer under warranty so I’m ok taking tools to it, so long as I don’t break it. 
Any thoughts?
Thanks in advance,
Jay
Figured it out.
There are 3 screws underneath the front sticker. Removing the sticker and the 3 screws allowed me to open the 100G case.
Unfortunately, it seems they use a special 3-pin power adapter so I had to cut the wires and splice it to my new Noctua fan.
Regardless, I’m back up and running, now silently.
