Earlier this year I purchased the HAVN HS420 to use as the case for my personal rig, however it did not arrive in time so I used the BeQuiet Light Base 900 instead... and the loop temp was hotter than I wanted... so I started all over and redid things the way I should have from the start... and it turned out epic! Enjoy this VLOG where I show you the entire process from beginning to end!
