This is on scan as a today only deal:
Xigmatek AIO-S80DP All-in-1 liquid cooling system (x2 80mm Rad/x2Tank/12v Pump/80m Fan/Copper Block)
http://www.scan.co.uk/product.aspx?ProductId=22836
Being an Air man, I have no clue what-so-ever as to whats needed to water cool a PC...however the "All in One" term used by scan would lead me to believe that this is the full kit.
However priced at £30 I really doubt that it is.
Can anyone shed some light as to what else would be needed to make this a kit?
Also I guess this would not be able to be modified to also cool a GPU?
