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.
Something like this that already has a drive build in (these come in varying sizes from smaller than this up to multi TB raids).
Several linux distros like this (wait for 2.0 release), and this would do the trick also.
As far as booting from a CD/DVD or flash drive, look for a linux live cd with the features you want or get a mobo that can boot from USB and install your distro/os to that flash drive. Do some searching in this forum (nas or home nas, for example) and you will find more of what you are looking for. Good luck.
