1000D - How to remove the roof?

[Eartpukaet]

Just received my 1000D for a big build. I will mount a 420 rad on top and need to make some modifications. Maybe this is simple, but how does one easily remove the top of the 1000D?

 

That is, the center glass panel with the two 'wings'? I can't see any screws, so does it simply pop off? Just weary of putting too much pressure on it.

 

Thanks!

Isn't it wonderful how much simpler it is to live with the discomfort merely knowing that you will soon have a break from it?
