So my GF got me this nice engraved thumbdrive case but it's only 1gb and I was wondering if anyone could offer up some replacement internals that would fit inside the case. Pics for reference and size, the grid is a 1x1".

As you can see in the pic, the board itself is about 1"x.5". I don't need an enormous one, but having enough room to put a movie or other files and still hold my school things would be great. Thanks in advance guys
