Okay, I have NEVER built a PC before, and I'm running into some major problems. Any help with the following issues would be greatly appreciated! 1. There is a 4-pin header on the motherboard labeled "ATX 12V". This obviously needs to be hooked up, correct? My power supply has no such connector block, although it DOES have an 8-pin block that "splits" giving you a 4-pin block. Does this get connected to the "ATX 12V" header? 2. My 3 case fans all have fairly large 4-pin connector blocks. These do in fact fit into certain connectors off the PSU. I will assume that these do in fact belong hooked up directly to the PSU? 3. How does the hard drive get installed? Unlike the optical drive, you have to slide the HD in from the back??? 4. Does it matter which drives get hooked up to which SATA headers on the motherboard? 5. Lastly, regarding certain power connectors off the front of the case, the colored wire with the little triangle on the connector block is usually the positive wire, correct? Apologies for the newbie questions, but I do not want to fry anything!
