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.
Whoa...I either slept really long and BTX has become standard or you're confusing standard ATX cases with flipped mobos with the new BTX which is actually a new motherboard layout...and isn't mainstream.
The only BTX case I've ever seen is the Cooler Master Stacker. It does both ATX and BTX. You have to take it apart and turn it into a BTX though. They do however give you everything needed to do that.
