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.
For what it's worth old Drobo 4 bay units go for around $60-$80. They are flawed systems for sure but they are absolutely better than the cheap 4 bay units and their software raid implementations you'll find on Amazon and Newegg.
Throw in the 4 largest drives you have and see what you get...
Save as everyone else above. My 2600k system with 980ti/mobo/16gb RAM/Raid-0 SSD's is still fast enough for my 60hz/1200p monitor. Thats the limiting factor. A new monitor would drive my upgrades at this point, not cpu pricing.
