Raijintek's exhibit at Computex 2023 was a captivating showcase of their innovative products for water-cooling enthusiasts. The company turned heads with its all-black brushed aluminium finish components, beautifully augmented with RGB lighting. Raijintek started off with their CPU water blocks, engineered to provide efficient cooling for high-performance CPUs. The RGB lighting breathed life into the elegant all-black blocks, rendering them both practical and stylish. Also featured was their state-of-the-art pump and reservoir combinations, with the same design ethos and a spotlight on efficient operation. Using the same black design, Raijintek extended their design to their radiators, with efficient heat dissipation to keep systems cool. Furthermore, their distribution plates continued to impress with their sleek designs, offering optimal flow paths for cooling fluid. There was a Chinese-inspired mod that showed usage of the company's components in the modded build.
 
The company case lineup also ranged from mid-towers to full towers capable of accommodating E-ATX componentry and plenty of space for large GPUs and water cooling. You can see these cases below.
 
Some interesting PC cases, but I don't see any PC cases that I like.
