8 Insanely Overpowered PCs Built Just to Show Off (And How You Can Build One Too)

If you’ve ever wanted a computer that’s more than just a machine but a statement piece—something that screams luxury, power, and creativity—then you’re in the right place. Here’s a roundup of eight insanely overpowered PCs that were built purely to impress, and some advice on how you can create your own version of these masterpieces.

1. Project “Big O” by Origin PC

Specs: Dual PC and Console Combo, featuring an RTX 4090, Intel Core i9-13900KS, PlayStation 5, and Xbox Series X.

Origin’s “Big O” is the ultimate fusion of a gaming PC and next-gen consoles. It integrates a powerful PC build with both a PlayStation 5 and an Xbox Series X, providing the ultimate gaming experience in a single chassis. The case is custom designed to fit all components, cooled by custom water loops that keep temperatures in check, despite its colossal power requirements.

How You Can Build One: Start with a high-quality, large chassis like the Phanteks Enthoo 719 and add modular components. Water cooling is key to keeping this behemoth stable. You could even DIY a system to integrate your console if you have some technical know-how.

2. Linus Tech Tips’ “8-Player Gaming Setup”

Specs: Eight high-end mini-PCs powered by RTX 3080 GPUs all housed in a single massive frame.

Linus Tech Tips took things to the next level by putting together a single housing for eight mini-PCs, allowing eight players to game simultaneously. It’s an entire LAN party in one box, and each system is capable of delivering a phenomenal gaming experience independently.

How You Can Build One: While you may not need eight PCs, you can attempt to build a powerful multi-system in one case using virtualization software. Use a case like the Thermaltake Tower 900, which offers space for multiple motherboards and plenty of GPU real estate.

3. “The Desk PC” by Lian Li

Specs: Dual RTX 4090 GPUs, Intel Core i9-13900KS, and an integrated desk build.

Lian Li’s “Desk PC” is a literal desk that functions as a high-end gaming PC. It’s an eye-catching blend of a piece of furniture and a computer, with RGB lighting illuminating the workspace. The cooling is primarily managed by custom liquid loops that not only ensure performance but also act as visual art.

How You Can Build One: Purchase a Lian Li DK-05 desk and start building! You will need to know your way around custom water cooling, as this kind of build requires extensive planning for tube routing, pump placement, and radiator fitting.

4. “Crystal Dreams” by PCJunkieMods

Specs: Custom liquid-cooled RTX 4090 setup, Intel Core i9-13900KS, RGB lighting, glass paneling.

The “Crystal Dreams” PC is about creating the most beautiful aesthetic possible while maintaining peak performance. The build uses tempered glass, clear tubing, and dazzling RGB lighting to craft a crystalline visual effect. The custom loops are arranged in perfect symmetry, making it as much a work of art as a functional machine.

How You Can Build One: Custom water cooling is your best friend here. Invest in a high-quality glass chassis and use plenty of transparent components to create a clean aesthetic. It’s a challenging build, but the results can be spectacular.

5. “The Aquarius” by EKWB

Specs: Complete water-cooling dominance with multiple RTX GPUs and Threadripper CPU.

EKWB’s “Aquarius” build is a showcase of the power of water cooling, with three separate loops for CPU, GPU, and RAM. It features numerous radiators and powerful D5 pumps to circulate the coolant, providing the highest level of overclocking capability with extreme stability.

How You Can Build One: Buy a motherboard that supports multiple GPUs and ensure that your chassis is capable of holding several radiators. Water blocks for RAM are less common, but companies like EKWB can provide the necessary components if you’re aiming to go all out.

6. “NVIDIA’s RTX 4090 Showpiece”

Specs: Multiple RTX 4090 GPUs, 8K video rendering capability, and AI computation setup.

This machine was built by NVIDIA specifically to show off the capabilities of the RTX 4090. It’s built with one purpose: to provide maximum power for 8K gaming and video production. It uses a workstation chassis and is cooled by a series of interconnected radiators.

How You Can Build One: Get yourself a workstation case like the Cooler Master Cosmos C700M and fill it with as much GPU power as your motherboard can handle. Cooling is key here, so consider using both air and liquid hybrid coolers for maximum effect.

7. “Star Wars Tie Fighter PC” by NZXT

Specs: Custom-shaped chassis, RTX 4090 GPU, AMD Ryzen 9 7950X CPU, themed cooling system.

The “Tie Fighter” PC mod is shaped like a Star Wars Tie Fighter, featuring themed lighting and custom cooling inspired by the movie. This machine screams power and fandom, demonstrating that overpowered PCs can also tell a story.

How You Can Build One: While building a custom-shaped PC might require some fabrication skills, you can start by designing or buying themed parts and adding your own touches. NZXT offers some Star Wars components, and you can custom paint and modify other parts to match the theme.

8. “Thermaltake Reactor” – 20 GPU Folding Rig

Specs: 20 Nvidia GPUs, AMD EPYC Processor, dedicated for folding and rendering.

This overpowered beast was built for a different purpose—scientific computations like protein folding. Thermaltake’s build features a staggering 20 GPUs, making it one of the most powerful desktop systems on the planet. It’s designed to generate enormous computing power in a relatively small form factor.

How You Can Build One: Consider a mining frame or large tower case with GPU support. Connect everything with riser cables and be ready to handle the power consumption. Ensure you have a robust PSU solution—likely multiple units to manage the power effectively.

How You Can Build Your Own Overpowered PC

• Pick a Purpose: Decide what you want your overpowered PC to do. Is it for gaming, rendering, or simply showing off? Each purpose dictates the components and the cooling solutions you’ll need.

• Invest in Cooling: Custom water cooling is a common theme in these builds, as keeping high-powered components cool is essential. Spend time learning about loop setup, as it’s both an art and a science.

• Customization: Whether it’s a themed PC or an unusual case design, the customization is what makes these PCs stand out. Acrylic panels, RGB lighting, and even complete case mods can transform a high-spec build into a showcase piece.

• Power Requirements: Many of these PCs require significantly more power than a standard build. Be prepared to invest in high-capacity PSUs, and consider options like dual power supply units for the most demanding setups.

• Plan for the Long-Term: Building one of these machines is a project that takes time, patience, and skill. Make sure you plan each step, have the necessary parts ready, and give yourself plenty of room to adjust and iterate as you go.

An overpowered PC isn’t just about performance—it’s a form of expression, a way to show off creativity, technical prowess, and a love for technology. Building your own could be the ultimate way to create something uniquely yours that stands out among enthusiasts.
