I have had a Koolance PC3-725 for about 18 months and it's very good for what it is. If you work on the basis that you are getting a £130 case plus a £55 window panel then you are paying £170 for the water-cooling installation. You don't get any blocks so you need to budget about £60 for that depending on which ones you choose and how much you want to cool.
The pro's?
It's very well fitted
It's easy to access the cooling settings
On low speed it's very quiet and it cools most things quite efficiently
The con's?
It sticks up out of the top of the case and doesn't do much for the looks
It still obscures the top 5.25" bay so you may as well have fitted it flush with the case roof.
It's not the best water-cooled case you can buy for £350 anymore
There are several people (no names, as they are deemed to be competitors) who will cut your case and fit a radiator in the roof for about £25+parts. They'll also pipe it up for you with a good pump, res or T-line, blocks and anything you want. You'll get good advice on how big a system to buy based on what you want to cool and there is at least one guy who you can send you existing computer to and he'll transfer all the parts and build your new-one up for £50 and he's fully insured so if he makes a mess he pays for new bits.
My advice would be to check out a couple of specialist water-cooling places and ask for a quote on a V1000+ II with a windowed side panel and your choice of components all built up and filled and it will probably cost the same as the Koolance, but work a darn site better.
