I am about to RMA my first and definitely my last Kolink anything,
https://www.overclockers.co.uk/kolink-void-rgb-midi-tower-case-black-window-ca-04l-kk.html , never have a i seen a case that restricts airflow this bad, 3 fans in front, not a chance, 2 are obstructed with the plastic panel for the light show up front, and the 3rd fan will blow into the PSU compartment, as for the roof, you have about 1mm in the honeycomb area, its a hot box waiting to happen, not daring to risk the 3600/5600XT build that was going in it for the daughter, ah well, live and learn, oh and no manual included and a bag of screws that are good for nothing.
