New build, question regarding power and water cooling

Hey everyone,

I am planning a new build in the next few months, and have come up with the following as a working selection:

Intel Core i5 3570K 3.4GHz Socket 1155
Corsair Hydro Series H60 High Performance Liquid CPU Cooler
Gigabyte GA-Z77-D3H Socket 1155 VGA DVI HDMI 8 Channel Audio ATX Motherboard
Corsair 8GB (2x4GB) DDR3 1600MHz XMS3 Memory Kit CL9 1.65V
Gigabyte GTX 670 Windforce 3X 2GB GDDR5 Dual DVI HDMI DisplayPort PCI-E Graphics Card
CM Storm Scout Case
Coolermaster Silent Pro 700W Modular PSU
Samsung SH-222BB 22x DVD±RW DL & RAM SATA Optical Drive
Creative SoundBlaster X-Fi Xtreme Audio Soundcard
SanDisk 240GB Extreme SSD - 2.5" SATA-III

My questions are the following:

With the above components, is the PSU sufficient for the build? Note that I may still decide to add a high capacity mechanical HDD at a later date, although I do also have a NAS server that I run also for most bulk stuff.

Also with the case selected, how well will a water cooling solution work?

The above components have been priced at approx. £1000, with the case and power supply currently as a special offer bundle together. This is about the limit of my spare budget currently, so try to keep around that  

Any advice/comments/etc are greatly welcome, as I want to get the build right first time and get up and running without fussing with returning incorrect/incompatible parts.

Many thanks,

Stu
