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 I don't want to use the think ass window trim stuff to hold the window to the side panel, what's the best way to keep the window connected to the panel?
Drilling out the holes and pop-riveting it in place works well; depending on the look your going for.
if you want to be able to swap it out with other color plexi's then go for some screws, this way you can also change the look on the outside by changing the type of nut you put on it.
