KitGuru tried the PC Specialist LS-M02 Custom Watercooled System
A quote from the article:
Liquid Series from PC Specialist is a new range of PCs that employ a custom loop liquid cooling system to deliver maximum performance along with stunning visual appeal. The LS-M02 we have for review is an example of the way Liquid Series works and uses a mainstream gaming specification with a price that comes in just under £2,000.PC Specialist LS-M02 Custom Watercooled System Review @ Kitguru
If you decide to configure your own PC you have the choice of Z170/Skylake or X99/Haswell-E hardware (Intel only, no AMD) and can select from a choice of 16 cases, four different cooling systems, as many as three graphics cards and a huge number of other options. The permutations are almost limitless so it makes a good deal of sense to select a pre-configured PC such as LS-M02.
