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.
Just to let you know we have a nice little Linux sub-section to post these questions in.
This question is also asked daily so you may want to try the search feature.
To answer you questions, pretty much most distros will work will as long as you avoid using CPU intensive apps and GUI's like KDE. There are som lite GUI's you can install but you will need to get your hands dirty a little.
