If all you want to do is repaint the red and black shroud, it shouldn't be too hard to take off.
But I think it may be connected to the heatsink.
Tom's did a teardown of the msi 1050, looks like you only need to remove the 4 screws in the back to get the heatsink off.
Keep in mind you'll have to clean off and reapply the thermal paste over the GPU if you do take it off.

Should be pretty similar to this:
