Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
If you are worried how it looks with light shining through those mobo holes you can always cover them with same tape. Might look aesthetically better to not have the light shining through. If your worried about dust coming into those holes, then tape would fix that too, or just make sure you have enough positive pressure to ensure it's not drawing in air. But I too will be running with it off(waiting to complete my current build).
