Whether you’re brand new to PC gaming or have been doing it for years, building your PC is something that you should try. All of the components to a PC are important, but they also have one thing in common. They all go inside the case.

The case is arguably one of the most important pieces of a PC build since there are so many options that suit your build’s needs. Want a case that offers great customization and is big enough to house all the state of the art components? Well, an inverted ATX case is perfect for that!

But what exactly is an inverted ATX case? Put simply, its a computer case that allows you to flip the motherboard upside down so your graphics card is at the top. Why is that important?

  • Left-Hand Setups – Allows for setups with your computer on the left while still having a window into the PC in plain view
  • It’s unique – Let’s be honest, many PC setups are all about looks. An inverted setup is sure to set you apart from the norm.
  • Customization – The inverted setup allows you to move different components around in the case that aren’t possible with a traditional ATX setup
