The be quiet! Pure Base 501 mainstream case series was revealed around late October last year, but it is possible that a fairly new product has not reached all international markets. Company representatives were keen to show off the compact Pure Base 501 Air Flow White model at this year's CES trade event. TechPowerUp spent some time looking at the version sporting a solid/closed steel side panel—ideal for builders who are not fussed about displaying their system's innards.

The flashier Pure Base 501 Air Flow White with a glass side panel was also within reach at be quiet!'s Las Vegas suite. TPU checked out the case's very clean interior layout and spotted the two (pre-fitted as standard) Pure Wings 3 140 mm PWM fans. be quiet! has placed emphasis on the Pure Base 501's traditional aesthetic—devoid of loud RGB lighting zones. The case has been designed with versatility in mind, and its smart cable routing system was on display at CES 2025. TechPowerUp will be looking forward to the potential arrival of a review unit!
