Hey guys, almost done with my first build, just had a quick question. I have an nzxt s340 case which has a hdd indicate on it, I have not installed my os yet, I haven't even hooked it up to a monitor yet, waiting for my graphics card to get in, but I have powered it on and the power led works and all the fans come on also. My question is should the hdd light be on, or will it not start blinking till I actually boot into the bios and install my os?
