5 Best Inverted ATX PC Cases for 2024

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

• 23.9 pounds

The best mid-range option in this article is the Segotep T1. It’s extremely unique to this list with its vertical GPU mount design. There’s tons of room inside, allowing for GPU’s up to 13.6 inches long. The vertical mount design allows for your GPU to be in between the airflow of your intake and exhaust fans on the front and back, allowing for maximum airflow and ultimately, lower temperatures.

When it comes to cable management, the Segotep T1 comes prepared. Featuring a port storage box at the top for I/O cables, and spacious area behind the motherboard with velcro. Keeping your build organized will be a breeze.

For fans of storage, the Segotep T1 can hold up to 6 drives depending on your mix of HDDs and SSDs. For cooling, the front can accommodate three 120mm or 140mm fans or a 360mm radiator. The back can hold three 120mm fans, two 140mm fans, or one 360mm radiator. Since the top has the cable storage box, only one 120mm fan can be attached there.

Aesthetically, it looks great. Offered in both black and white, you can match your setup perfectly. The side has a full tempered glass panel, and the front features a mesh and plastic see through panel, so RGB fans on the front are a great addition.

Pros:

• Vertical GPU mount
• Comes in black and white
• Multiple radiator and fan sizes supported

Cons:

• Not designed to support horizontal GPU placement in standard or inverted format
• Fans are not included

Best Budget: Thermaltake Core G3

Looking for a great option for your budget build? Check out the Thermaltake Core G3! While this case is the smallest and most affordable, it can still house a powerful mix of components for any state-of-the-art gaming PC.

Offering the ability to build in both horizontal and vertical inverted orientations, you can build your PC exactly how you want to. This case is similar to the Cooler Master Cosmos C700P because the windowed side panel only works on one side. However, this case is designed with that panel on the right side, so you’ll always be able to see inside your inverted right-facing builds.

This case is designed with water cooling in mind. The flexibility of GPU placement helps to route cooling where it has to go. You will have to do some planning ahead of time to make sure your water cooling fits the way you want it to, due to the smaller size, but it’s still more than possible to achieve.

Pros:

• Most affordable option.
• Designed for both horizontal and vertical inverted layouts.
• Designed with water cooling in mind.

Cons:

• No USB C port on the front I/O
