The new Cooler Master QUBE 540 is advertised as a highly versatile PC case with a relatively low price. Its dimensions of 42.5 x 42.5 x 22.5 cm make it compatible with mainboards in the ITX to E-ATX formats as well as graphics cards that are up to 41.5 cm long. Large circular openings on the front, back can be used to attach accessories directly to the case.

In addition to practical add-ons such as mounts for headphones, keyboards and smartphones, there are also decorative options like a chicken head or octopus tentacles. Meanwhile, a rotating base allows the case to turn by 360 degrees as long as there are no cables in the way.

My fascination for technology goes back a long way to the Pentium II era. Modding, overclocking and treasuring computer hardware has since become an integral part of my life. As a student, I further developed a keen interest in mobile technologies that can make the stressful college life so much easier. After I fell in love with the creation of digital content while working in a marketing position, I now scour the web to bring you the most exciting topics in the world of tech. Outside the office, I’m particularly passionate about motorsports and mountain biking.
