Thermaltake CAPO X fits two PCs in one case, but needs careful cooling
Thermaltake’s CAPO X holds two independent computers in one case, with one system stacked above the other.
A test paired an AMD Ryzen 7 and Radeon graphics card in the upper compartment with an Intel Core Ultra processor and GeForce graphics card below.
Both systems stayed stable during simultaneous stress tests, but the upper PC ran about 5°C warmer than when tested alone.
The review linked that rise to heat from the lower system affecting airflow, though it did not establish that every build would behave the same way.
The temperature increase calls for careful cooling, including choices about fan placement, speed and airflow between the compartments.
Building the case takes more work than a standard PC, because each system needs its own components and connections, and the case has no fan hub.
A faster rear exhaust fan or a separate fan controller could help builders manage heat and connections.
Thermaltake’s CAPO X is a full tower case designed to house two independent computers in one enclosure.
A review found both systems maintained stable temperatures during simultaneous stress testing.
The upper AMD system ran about 5°C warmer when both computers operated than when it ran alone.
The review attributed the difference to heat from the lower Intel system affecting airflow in the upper compartment.
The case requires careful cooling decisions and a more complex build than a conventional single-system case.
- Who
- Thermaltake makes the CAPO X case. A review tested it with AMD and Intel computer systems.
- What
- The CAPO X houses two independent computers in one case. Testing found the upper system ran about 5°C warmer when both were operating.
- When
- The review was published on 2026-10-25.
- Where
- In the Thermaltake CAPO X full tower case.
- Why
- The case is designed to accommodate two independent computer systems in one enclosure.
This story does not have two clearly opposing sides.
Temperatures climbed, then settled without substantial fluctuations in either compartment.
Both systems maintained stable temperatures, while the upper AMD system ran about 5°C warmer than when operating alone.
