Thermaltake Core V21 Micro Chassis (Black)

The Thermaltake CA-1D5-00S1WN-00 is a micro chassis that brings full-size performance to a desk, shelf, or entertainment center where space matters. Built around a cube layout, it gives every component its own clear airflow path while keeping the footprint small enough for apartments, dorm rooms, or compact gaming stations.

The internal frame is fully modular, so you decide how the system is arranged. Mount the motherboard in a vertical position to showcase a graphics card, or lay it flat to give a heavier CPU cooler extra support. Panels swap easily to match the orientation, and cable routing channels stay accessible either way.

Growth is part of the design. The chassis can stack with another Core V21, creating room for extra radiators, pumps, or even a second system that handles streaming and file storage. Builders planning a custom liquid loop will appreciate the added ceiling space and straightforward tubing runs.

Inside, you will find clearance for a graphics card up to 13.8 in, a CPU cooler up to 7.3 in, and six storage drives. Tool-free drive racks slide out when more room is needed for airflow or larger power supplies, and a removable dust filter sits under the PSU to keep debris away from delicate parts.

Thermal performance starts with a 7.9 in front fan that ships preinstalled, moving a high volume of air without added noise. The top panel accepts two 9.4 in radiators or matching fans, and additional mounts on the sides and rear let you fine-tune airflow for either air-cooling or water-cooling builds.

The Core V21 suits first-time builders who want an easy, compact gaming rig and veteran enthusiasts who need a platform for a showcase liquid-cooled system. It also works well in studios that need a quiet editing PC, or in home and small-office setups where floor space is limited but component flexibility is essential.
