hey guys currently this is my shoping list
https://secure.scan.co.uk/aspnet/Shop/SavedBasket/Show.aspx?Id=2a534ec572984746bb3b22afbd710b47
will give you a idea of what im goin to be working with
1st im looking to cool both cpu and gfx card with liquid im waiting on a reply from scan if they will do a pre blocked gfx card for me so not to void warenty if i buy off them.
2nd 1 or 2 loops?
if i go for 1 loop how much effect do you think sending heated water from one component to the other will make?
i was thinking in the 700d theres enough for a big rad at the top and a small rad where the back extractor fan is so i could have a small rad inbetween the 2 components sort of intermediary cooler.
3rd what makes models would you sugest and where would you sugest getting them from?
