I'm facing an issue where my GPU (a 3060) is being blocked by a heatsink on my motherboard, preventing it from seating properly in the PCIe slot. I'm considering two potential solutions: vertically mounting the GPU or cutting off a part of the plastic shell that seems to be interfering. Is it safe to modify the GPU in that way, or should I opt for the vertical mount instead?

In general, avoid modifications! If it doesn't fit, there's likely something wrong with component compatibility. You could also look into selling and getting parts that are guaranteed to fit together, which would save a lot of headaches in the long run.
Don't cut anything yet! First, double-check that you're using the top PCIe x16 slot. Make sure there's no leftover plastic on the heatsink either. Sometimes, reseating the motherboard or just using a quality riser cable for vertical mounting can be a safer fix.
Before doing anything drastic like cutting, I recommend trying the vertical mounting approach. It's not just safer but can also help prevent GPU sag in the future, especially with larger cards. Plus, cutting the GPU could mess with its cooling or even damage it.
If there's an available PCIe slot, try that out first. If not, vertical mounting is the best bet. But remember, cutting into the GPU can void warranties or cause serious issues, so it’s usually not advisable.
I agree with the other responses. A GPU's shroud does help direct airflow, and cutting it might reduce its effectiveness. Instead, consider using a PCIe extension cable if you're going vertical; that way, you can position the card however you want without the risk of cutting it.
Just a heads up, consider airflow when mounting vertically. You don’t want to obstruct cooling.

Yeah, cutting can lead to unforeseen problems. Vertical mounts are usually a better option if you're having fit issues.
