Having a tool like this would be great. A paperclip isn't a bad idea either, but in a world of tool-less cases this is still frustrating. From my experience on the Sunmilo cases, you'll need to take the whole hard drive cage out every time you want to add a drive(and sometimes other things too). Without seeing the Stream case in person it's hard to say about that as well. I'm not saying it's a bad case or that people shouldn't buy it, for those who will build once and never touch it again it'll be great, but for those that like to change stuff a lot this style can be frustrating.
