All,
I'm building a computer for the first time. Here's where I am right now:

Cooling system COOLER MASTER Hyper 212 EVO
Thermal compound Arctic Silver 5 Thermal Compound - OEM
Motherboard GIGABYTE GA-Z68XP-UD3
RAM CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
Graphics Card 2x EVGA 01G-P3-1561-AR GeForce GTX 560 Ti FPB (Fermi) 1GB
Hard Drive OCZ Agility 3 120 GB
Hard Drive SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM
Power Supply CORSAIR Professional Series HX850
DVD Burner LG 12x WH12LS30 Blu-ray Burner

I'm leaning towards the Corsair 400R...

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

...because of the reliability of the brand and the relative calmness of the look (I don't like flashy LEDs and a case that looks like sci-fi armor plating)

I plan on slight OC'ing and therefore want the cooling to be superb so this computer lasts a long time. Toms recent article on proper case cooling makes the case for both top case fans (in general) and side fans (for SLI/crossfire builds).

http://www.tomshardware.com/reviews/cooling-airflow-hea...

I'd like a case with good side and top cooling so I see my options as the following:

Top cooling:

1. add 2x120mm fans to the top ($7 - http://www.newegg.com/Product/Product.aspx?Item=N82E168... )

2. add 2x140mm fans to the top ($20 - http://www.newegg.com/Product/Product.aspx?Item=N82E168... )

Side cooling:

1. add 2x120mm fans to the side (same as above)

2. add 2x140mm fans to the side (same as above)

3. Upgrade to the Corsair Carbide Series 500R, which has a 200mm side fan (extra $45 after rebate for the case - http://www.newegg.com/Product/Product.aspx?Item=N82E168...)

Here are my questions:
1. Are the 140mm worth the extra cost (top and/or side)?
2. Is the upgrade to the 500R with the 200mm fan worth the extra cost?
3. Any other case suggestions (that don't look like sci-fi armor plating)?

I would personally not get any fans until I've bought the case.

I would setup the cpu cooler vertically so that air flows from the front to the cooler out the rear fan.
The front two fans would supply cool air to the gpu and since the gpus are reference and exhaust heat to the out side I don't think you would need any extra fans.

I think the setup is ok already. If it isn't you can buy more fans later. You don't need faster airflow. All you need is sufficient airflow. Once you have sufficient airflow you can't get any cooler.

As long as you can add fans to mod out the 400R you can opt for either that one or the 500R.

The 200 mm fan in the Corsair produces about 80 cfm and is very quiet (lower rpms than a 120 mm). I was not satisfied with the 80 cfm in the Corsair 600T for the top ventillation and replaced the 200 mm fan with two 120 Xigmatec Crystal fans producing about 63 cfm apiece.

The Corsair 400 and 500 are identical except for the fans: I go with the 400; fans are cheap.

I recommend that you add two of these to the side window for great quiet cooling: http://www.newegg.com/Product/Product.aspx?Item=N82E168.... They have 10 X MTBF over the Xigmatec fans.

The CM 120 fans you refer to are OK, but they only put out 40 cfm: hardly ideal for a well cooled machine. If you go with 120s go with Xigmatec or Cougar fans. Quieter and they produce 60 + cfm.
