Know before you buy
Yes, the Core V21 features a modular, stackable design that allows you to connect multiple units. This is ideal if you want to expand your cooling capacity or create a dual-system setup.
The case supports GPUs up to 350mm in length, which covers the vast majority of modern high-end graphics cards. You should have plenty of room for most triple-fan models.
Absolutely. The Core V21 is specifically designed for DIY liquid cooling and supports radiator sizes ranging from 120mm up to 360mm, providing significant flexibility for your loop configuration.
The case supports both vertical and horizontal motherboard placement, which is great for aesthetics or specific airflow needs. Just ensure your CPU cooler height does not exceed 185mm, regardless of the orientation you choose.
The dual-chamber layout separates your heat-generating components, like the CPU and GPU, from the power supply and storage drives. This isolation allows for more efficient airflow and keeps your critical components cooler.
The case includes shockproof rubber gaskets on the PSU bracket, which help dampen vibrations from the power supply. While it isn't a sound-proofed silent case, these small additions help minimize operational noise.
