I need something to auto open a custom case door. The door will open vertically, and I want to know what i should use to open it. I would like to be able to open/close it at the touch of a button(even when the pc is off). I'm on a bit of a small budget, so i would like to find a cheap solution as this is not the most crucial part of the case. What should i use, and where is a good place to get them? Also are there any tutorials on this type of thing? Thanks for the info
