I like this idea of placing them inside the tower, either on the PSU shroud or on top of GPU, however I am super sketch of doing so I'm afraid that they may melt, paint may come off and etc. I have a Deadpool gamer pop and I keep him at my desk but love the idea of placing him on the GPU or even the Shroud of PSU. I have seen pics of people doing so but I just think they don't really keep them inside their rig.
