Thoughts about my new system build (about to place the order). Including keyboard and monitor choice

[shanakarr]

Keyboard and mouse - Logitech MK 550 wireless desktop combo
Monitor - ASUS VX238H 23" 1ms HDMI Full HD LED Monitor with Speaker
CPU - i7 4770K
SSD - Crucial m500 120GB SATA II
Case - Fractal R4
Graphics card - Sapphire AMD Radeon R9 270X 2GB TOXIC OC
PSU- Thermaltake W0356 Litepower 700W or Corsair CX-600 V3
RAM - G.SKILL RipjawsX 16GB (2x 8GB)
Wireless card - $20
CD Drive - $20
HDD - Western Digital WD20EZRX WD 2TB
CPU Cooler - Noctua NH-D14
Additional fan - Fractal Design Silent Series R2 120mm Fan

Some questions for everyone.
1) What do you think of the PSU? Can i go for a lower voltage one? Is thethermltake any good? I don't want to spend more than $100 on it. Another choice was the Zalman ZM-700-GV 80 Plus Bronze Power Supply. How do you compare the two? What are your thoughts on the Corsair CX-600 V3 80+
Any other suggestions you might have would also be appreciated on the PSU choice.
2) Should i get an additonal fan for this case? Is it worth it? Can you please tell me why if so.
3) What do you make of:
a) the keyboard choice? Looking for something that i can type at length with. Not so much for gaming, but an all round versatile keyboard. Looking at MK models for now, but open to other suggestions. Under $100.
b) the monitor choice? Under $200 over here. looking for something 2ms and under.
4) What do you make of the overall build? It will be used for non-gaming about 70% of the time, particularly programming.

Thanks for all your input!

1. None of the above - the Corsair CX is relatively weak compared to the rest of their line. Thermaltake and Zalman PSUs are junk, and on a build for your budget I wouldn't subject to a sub par unit. Go with a Seasonic G series or an XFX Pro series instead - far better units.

2. No - no reason to splurge on fans until you have your build up and running.

3. Low end Logitech units aren't my personal favorites. The keyboards feel like you're typing on cardboard. You could definitely get a nice mechanical keyboard like this for $70: http://www.newegg.com/Product/Product.aspx?Item=N82E16823162029

b) The monitor choice looks good.

4. It's decent - there's no reason for a super powerful cooler like a D14 but overall it could use a bit of tweaking:
