Ok I got all the components listed except for the fact that I opted for a seasonic modular power supply instead. For 10$ I figured what the heck.
I have most of the computer assembled the motherboard is installed along with all the other essential components. All that needs to be done now is to wire everything in. This is where I hit a bit of a snag, I got the Antec 300 series case and it has two case fans build in. I also purchased three other cooler master case fans to fill the extra fan ports. The problem is they are all three pin while the several connections on my mother board are four. I do have one three pin header on the motherboard but that's it. What do I need to do if I want to connect all five of the case fans to the power supply. The three cooler master fans came with some kind of molex connector that has both male and female ends on it along with a three pin fan plug. not sure what this is for. In the description it says that the fans comes with a three to four pin adapter. I assume that this connector is the adapter but I'm not quite sure how it hooks in. And it doesn't solve the problem with the two case fans that came with the case. If someone could give any suggestions it would be much appreciated.
I'm assuming you followed the list I came up with in post #4? Cool.
I don't have a modular power supply in here, and haven't found the extra wires to be too much of an issue (this seasonic has quite a few though - for instance, it has 2 CPU 4/8-pin connectors, and the only reason you'd need that is for a server board - and who has one of those?). I put the rest in the area to the right of the hard drive bays (there are a few cable ties in there btw for that reason). I looked into modular ones at the time, but they were a bit too expensive in my opinion. (probably overpriced for what they are) I'm assuming you got the M12II. What I find is that, unless you have a side window, you don't really need to worry about a mess of wires as long as they don't obstruct airflow. Either way, good choice.
In my Antec 300, I set the top 140mm and rear 120mm fans to low, and there's the CPU fan (connected to the motherboard CPU_fan header), and I didn't add any others. That seems to work pretty well, temps and noise are fine. I think intake fans don't make a huge difference, and you'll probably hear them more than rear fans. Note that my CPU cooler, a cooler master TX3, is also pointing toward the back (probably a bit redundant, with the rear fan pointing that way too). You can plug a 3-pin fan into a 4-pin connector and vise versa. 4-pin fans can be controlled via PWM (signal) while 3-pin ones must be controlled via voltage. (you can control a 4-pin fan via voltage if you want though) If either the plug, fan, or both are 3-pin, you'll get voltage speed control. Note: beware - you can get a 3-pin to molex adapter for fans so that you can connect them to the power supply, but unless the fan has a temp sensor or speed selector, it'll run full blast all the time , making a ton more noise than necessary.
Your components probably create a similar amount of heat compared to mine (my gpu has a 116W TDP, yours is 108W, both of our CPUs are 95W...), so you're fine just setting the 2 included case fans to low and not using any others besides the cpu fan. If I were you, I'd return the extra case fans and maybe spend the money on an aftermarket cpu cooler instead (as I said, something like a cooler master tx3 or 212 allows you to do a bit of overclocking, and even if you don't, you'll still drastically cut fan noise when the cpu is under load), since in general it'll make more difference. Those extra fans will just give you a bunch more noise with little gain. Right now, my case is 25C (idle).
Fyi, don't bother with hard drive cooling - the outtake fans will force air in through the front grill, pulling the air over the hard drives. I have two drives in here (I left a bay or two inbetween them though), and typically one's at 30C (the wd black) and the other is at 25C (the samsung). See my sig for my PC's specs. Those temps are well within the safe range for hard drives. (typically you don't want them over 40-45C) I haven't yet seen what temps in the summer are like with this case (I got it a month or two ago), but in my old case, they were about 5C higher than in winter, still pretty good.
