Scythe gental typhoons are great for water cooling or anything else that has a need for good static pressure.
I'd not say they are the best of fans generally as you can get fans far cheaper that will perform just as well for far less.
The sliverstone FN122 is a great low noise fan for under £5 http://www.scan.co.uk/Products/120mm...bearing-design
The Shrakoon system fans are decent as well http://www.scan.co.uk/Products/120mm...8A%29-Case-Fan
For a bit more the thermalright fans are worth a look http://www.scan.co.uk/Products/Therm...at-max-1000RPM
The thing to remember when looking at fan of the same size is that rpm is the most important factor in terms of air flow & noise
Execpt when you get into the 1000rpm or less area when motor &/or bareing noise starts to become louder than the sound of the fan
Still even then the loudest motor/bareing is still pretty quiet.
EDIT:the sunbeam cases are also screwless, the main the going for the coolermasters is slightly higher build quality, a different look and internal layout.
the sunbeam's can only take 3 hard drives, where as the CM elite 330 can take 5 and has less restrictive air flow over the hard drives.
Although I personally prefur the 90 degree hard drive layout as I find it far eaiser to access hard drives.
