Hello guys! Why are we talking about this in cooling?
For case or PSU related topics, post em in here:

Just so im not watering this sucker down with "post in PSUs!!!" spam, I agree with Silversinksam about getting PC Power and Cooling if you have the money, but unless you live in a REALLY hot climate (power supplies with higher temperatures produce less power) or have ALOT of power-sucking gizmos in your computer, I would recomend saving your money and getting something less overkill. A 510 watt PC Power and Cooling is probably the equivilent or better than any other 600+ watt PSU. Just to give you an idea on how much power you actually NEED, I could run 7 case fans, a 7200RPM HDD, CD burner, and the stuff in my sig on a
300watt feather light, no name brand that came with my $19.95 "call now and get a free pearing knife!" case. And, it did that with an ambient temperature of 80°F.
Now, there is the question about reliability, yes, a 300-400 watt POS could power it, but how long could it power it before dying, or exploding and injuring you and everyone that lives within a 15 mile radius? That is why I recomend getting something that is of a bit more quality, but sometimes, we go overkill on our PSU's and buy what is not really needed. As you can see in my sig.....I did that..but it is still a cheapo.
Now on the other hand, if you have ALOT of stuff, like 20 case fans, 14 cold cathods, a Prescott overclocked to 5Ghz and 3.0Vcore, a 4 terrabyte 15k RPM raid array, 5 DVD burners all "backing up" your purchased DVD's at once, and whole lot of other ****, then yes, go for something more powerful.

As for SATA, you can purchase adaptors from many computer stores, local(unless you live in some god-awful place like the jungles in South asjhfsomewhereajsdhlastan) or on the internet for a decent price.
