The alternate is essentially the same but with an ASUS SABERTOOTH Z77 (Intel Z77 Chipset) (Features Thermal Armor and Thermal Radar) and overclock 2nd stage.

Any advice to either making the build more economically efficient or maximize performance within budget, will be greatly appreciated.

Extra : I am considering getting BenQ RL2450HT ($200) as a monitor [although I do not play RTS, more FPS]. I was wondering if anyone has had experience with this BenQ model, or if the BenQ XL2420T ($370) is worth being almost double the price of the RL2450HT.

Thanks for the reply, bprat22.

I think I would prefer fans. I have never had a PC with liquid cooling and I'm not too sure how to deal with problems. How would I be able to tell if the Noctua D14 fits inside a certain chassis?

Chassis I chose :
1. Front:12cm Fan x 1
2. Rear: 12cm Fan x 1
3. Top:12cm Fan x 1 (Maximum Supports 12cm Fan x 2)
4. Side:22cm LED Fan with switch x 1 (Maximum Supports 12cm Fan x 6)
5. Water-Cooling Hole Ready

and the Noctua
140 x 140 x 25 mm
120 x 120 x 25 mm
Heatsink Dimensions
158 x 126 x 120 mm(with fan)

Would the Corsair Carbide 500R be able to hold the fan?
Cooling(x6) 120mm/140mm fan mounts, (x4) 120mm fan mounts, Includes (x1) 200mm side panel fan, (x2) front-mounted 120mm fans, and (x1) rear 120mm fan
OR
CoolMaster Elite 430
Top: 120 mm fan x 2 (optional)
Front: 120 mm blue LED fan x 1, 140 mm fan x 1 (optional)
Rear: 80/90/120 mm fan x 1 (optional)
Side: 120mm fan x 1 (optional)
Bottom: 80/90/120 mm fan x 1 (optional)

Thanks for any suggestions!
