Hello this in my ion mod submission I had an old router sitting around and i figured i could probably fit the board some memory and a SSD in if i stacked them on top of each other, for external storage i was thinking that there could be a way to slide the drive unto the bottom with a rail mechanism with a clip at the end and this would also allow you to make a stand or a vesa mount on the bottom similar to what home theater speakers use so you can mount them on a wall or desk. i wasn't too sure what you guys were looking for so hopefully with some input i can clean it up a little.
