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.
I've been running a Seagate Momentus XT 750gb hybrid in my laptop for the last two years. I've been very pleased with it. It boots nearly as quickly as an SSD, and in general use it feels like a fast desktop drive. I even bought a second one as a spare a few months ago.
That said, no one...
How about an external USB sound card? They're not terribly expensive, and several on the Egg are supported for Windows/Linux/MacOSX, if that's a consideration.
That cooler will definitely not fit if you include an optical drive in your build. In the GD04/GD05, the optical drive overhangs the CPU socket, so a low profile HSF is required. In mine, the stock Intel i3 heatsink fits, but anything much taller would not.
