How to open NEO3 case

[Goney3]

Hello,
I've been wanting to check my heatsink since my temperatures are 63°C at idle and peaks around 85°C while under load. However the case appears impossible to open. What would you suggest for opening it safely?

Thank you!

I used an old credit card and worked my way around the device. There is a tab on each side. I am attaching an image showing the tab on the "front" of the case (the side with the alignment arrows for the case). My opening tool is under the tab for that side. I worked my way around it and it popped open. It wasn't the easiest and this little marshmallow will be replaced as soon as FriendlyElec releases a metal case or anything better.
