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.
No good ones that I have seen. Since most blocks come with clear tops you could mod one any color you wanted. You could check out the orac^3 project at www.bit-tech.net to get an idea of how to make your acrylic glow.
The Thermaltake bigwater has a blue led on it. It does not have a sensor though. xoxide has it for $53. You might be able to find it cheaper I didn't look very hard. The par number is CL-W0010.
