Hi Eliana, Great questions! The manufacturer does not really test for weight capacity however, a good guideline to use is to evenly distribute the weight across the shelves. Additionally, I would suggest keeping the weight around 30-45 lbs to prevent the shelves from sagging over time. As for the media hole, the manufacturer is not able to customize at all, however, once you have it in your possession, you are free to modify it according to your needs. I hope this helps!
