Compact PC cases keep getting more popular as GPUs grow larger and desks get smaller. The challenge is simple: you are trying to dissipate the same heat in a fraction of the volume. Getting it right is a balance of GPU clearance, cooling provision and intelligent internal layout.
Clearance is the first constraint
Before anything else, a compact case has to physically accept the GPU, the cooler and the power supply you intend to use. SNY lists maximum GPU length and cooler height per model so a builder can verify fit before purchase instead of discovering it at assembly.
A compact case that balances GPU clearance, cooling and modular design is what makes small builds practical rather than compromises.
Cooling that scales with the case
In a small volume, pre-installed fans and a clear intake path do more than raw fan count. Pairing a compact case with an efficient air or liquid cooler and a sensible fan curve keeps noise down while protecting the GPU's boost behaviour under sustained load.
