My first build and have two questions already. Antec case came with fan mounted but what do I do with the 4" cable with speed control swith, do I try to route it outside of case? I'm afraid to just leave it and have it get tangled in fan. Asus M4A88TD-V EVO/USB3 mobo came with 4 SATA cables, two are 6.0 Gbs and two are 3.0 Gbs. What is the difference and what should I use where, they are all the saqme length?
