I cut my finger last night during setup my brother PC. I was cut by sharp edge of Cooler Master casing when I try to remove front panel to install DVD writer. The Cooler Master Elite 330 casing internal design is bad and dangerous with all the sharp edges around. Besides, they did not include steps to remove front panel in the manual. I am not sure which sharp edges cut me but definitely one of them. Therefore, be careful when trying to remove the front panel.
