? yea i don't see why not. Get some big Sticker type material .. draw out your design and cut with a exacto knife or so.
for the time effort it takes, your way better off just getting the sticker. But imo those designs are stupid. If your going with a window Kit, people wanna look inside and admire the case, it will be dumb to have a window kit and then a huge sticker blocking it. i never understood that idea. But anyway.. I ordered the sqaure window kit made for the pc-60. and my next mod is going to be Carbon Fiber on the outside and where i feel it should go.
I will DEFF send pics to have them uploaded on my THG profile.
