Need help to pick new custom PC parts

[01BTC10]

This is my first custom build. This PC will be used for development and heavy virtualization with Debian as host system. I'm not a gamer. What do you think about my choices:


ASUS Z87-PLUS ATX LGA1150 Z87 DDR3 3PCI-E16 2PCI-E1 2PCI SLI SATA3 USB3.0 DVI HDMI Motherboard
Corsair CS750M CS Modular 80 Plus GOLD-RATE 750W 12V Power Supply
Intel Core i7 4770K Unlocked Quad Core 3.5GHZ Processor LGA1150 Haswell 8MB Cache Retail
Corsair Cooling Hydro Series H105 Extreme Performance 240MM CPU Cooler w/ Customizable PWM Fan Speed
2X Corsair Vengeance Black CMZ16GX3M2A1600C10 16GB 2X8GB DDR3-1600 CL10 1.5V Dual Channel Memory Kit

XFX Radeon HD 7870 Double D 1000MHZ 2GB 4.8GHZ GDDR5 DVI HDMI 2XMINIDP PCI-E Video Card
2X Nixeus 30IN Wqxga IPS High Resolution LCD Monitor 2560X1600 DVI VGA HDMI DisplayPort Speaker

Crucial M4 CT480M500SSD3 2.5in 480GB SATA III mSATA MLC Internal Solid State Drive (SSD) 7MM
2X RAID1:
Seagate Barracuda 2TB 7200RPM SATA3 64MB Cache 3.5in Internal Hard Drive

Zalman Z11 Plus Mid Tower ATX Case Black 4X5.25 1X3.5 5X3.5INT No PS Front USB3.0 & Audio
Be Quiet! Silent Wings 2 140mm 1000RPM 60.4CFM 15.8DBA Cooling Fan

My main concern are:

Does the CPU water cooler will fit with this case?
Does a 750W PSU will be sufficient for this build?
Is it possible to connect 2X Nixeus 30IN monitor on a XFX HD 7870 Double D?

Thanks for your help!
