This is a project that I have done in the past, but have never come across clear instructions on how to recreate. With that in mind, I decided to put together some instructions myself. While this is specifically focusing on using video game cases, this tutorial will work for DVD and Blu-Ray cases as well.

Step 1: Materials Needed

1 empty video game case of your choice (NOTE: you will not be able to store anything in the case once you are finished)
1 screwdriver
4-8 screws (depending on size of the case, durability, etc. In this tutorial I ended up using 6 screws)
1-2 L-shaped brackets (depending on size of the case and durability. I used two in this tutorial)
1 box cutter or X-Acto knife
A marker and/or pencil
(Optional) A level

Step 2: Preparing the Game Case

Decide on placement of the L-shaped brackets. For the best results, place them at equal distances from the edge, but be careful not to place them on top of the part that latches the case shut. Once placement is decided, draw guidelines on the case for where you are going to cut.

Once guidelines are made, cut out where you plan to install the brackets. Be sure to exercise caution when using sharp objects.

Step 3: Installing Brackets Into the Case

Next, mark where you plan on inserting the screws. If necessary, take your box cutter or X-Acto knife and create a small hole for your screw.

Once you're finished marking and cutting, secure the brackets in place by using screws and a screwdriver. If the game case does not close after this step, you may need to cut a little bit into the top part of the case.

Once the brackets are in place and the game case is closed, you're ready to hang up the shelf!

Step 4: Installing on the Wall

Once you have decided where to install the case, mark where you plan on screwing it in place. Use a level to ensure that your shelf is placed properly, if desired (in my case, I was just replacing an older shelf).

When placement is decided, screw the case into the wall.

Step 5: Conclusion

Just like that, you've got your very own "floating" video game shelf!

Each shelf can hold approximately 10 cases before the weight begins affecting it. If you want to make taller stacks of "floating" cases that still seem uniform, add in additional shelves as necessary.
