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.
You probably have few options. You have some pre-builts using laptop drives that can easily be had on ebay/Amazon. Any of those should do the job. I have a random brand one and have had no issues. That being said, *IF* you have a specific 5.25" drive you're enamored with, you can just slap it in an external enclosure from a reputable brand like Sabrent and you should be GTG.
