I wish more people did this, I sometimes have to convince people it's ok to remove stickers from the manufacturers. I recently painted my dryer and it's controls, the washers getting a treatment next. You can just pick up some nail polish and go to town on appliances if you want to start small.

Since you can't open the case and salvage much, engraving the case is a solid measure to confirm ownership.

Unrelated, but can you still choose to add engraving when you buy an Apple device?

they have deified the consumer product. they forget that the thing is useless after 5 to 10 years no matter how clean you keep it or what stickers you put on it. they forget it's just a tool
