PC Case Aquarium: The Complete 2025 Guide for a Transparent and Stylish Setup

Contrary to what the name might suggest, it is obviously not a real aquarium filled with water (and even less with fish!), but a case that highlights internal components through maximum transparency .

We are talking here:

• from tempered glass (often 4 or 5 mm)
• from side panels or even front or top panels completely transparent
• of a design that invitation to the exhibition , like a museum showcase dedicated to hardware

In general, the components are installed in a clearly visible manner , often with a vertical graphics card, good RGB lighting, and excellent cable management.🔍 Why choose an aquarium case in 2025?

It's THE number 1 reason. PC case aquarium , it's the choice of those who want their machine to be as beautiful as it is powerful. We are halfway between the gaming PC and the decorative object.

Do you have a Z790 motherboard with chrome heat sinks? An RTX 5090 with dynamic lighting? RGB RAM cascading? A custom watercooling system with colored liquid? This case is made for you.

With a closed case, you have no idea what's going on inside. There, at a glance, you can:

• See if all your fans are turning correctly
• Detect a leak in a watercooling system
• Observing the accumulation of dust
• Identify any cable or heating issues

Be careful with the size from your motherboard:

• Mini-ITX
• Micro-ATX
• ATX
• E-ATX

And also to the maximum length of the graphics card (especially with an RTX 4080/4090 that exceed 32 cm!), at the height of the CPU cooler , the number of hard drives, etc.

Glass, it doesn't breathe. So if the design is poorly thought out, you risk having high temperatures. It is absolutely necessary:

• of side or bottom air inlets
• a good extraction system
• enough space to install a 360mm radiator if needed

Does an aquarium case heat up more than a classic case?

Not necessarily. As long as it has a good ventilation system, it can be as efficient or even better ventilated than a traditional case. Just avoid purely aesthetic models without optimized airflow.

Can we install an AIO or custom watercooling in it?

Absolutely. It is even recommended. Aquarium cases are designed to accommodate 240 or 360 mm AIOs, and some offer vertical support with a reservoir.

Can they be easily transported?

They are a bit heavier, as glass weighs more than metal or plastic. But with suitable handles and sturdy packaging, it's doable.

Are all glass cases aquarium cases?

No. A case with just a transparent side panel is not an aquarium. What really defines this style is the design intended to showcase the interior, with multiple transparent sides and an "open" architecture.
