Wow what a can of worms i have opened.
From looking about it seems Mayhems is about the best fluid, It also seems the MD of the company is a Total tool, However reporting directly to a MD myself and being head of sales i become the buffer between the tool and the customers so i feel a little of the pain here.
My case is on display in our games room directly next to my Mrs PC and tbh i want it to look "cool" as we often have guests over for games nights etc. Im going to give the white Pastel a whirl based on the very mixed results here and all over the internet and make my mind up myself i think. I am prepared to do a Total strip down of the system if needed however i might change the fluid at the same time as moving over to hard tubing.
Really fancy giving the hard tubing a go. However will mean selling my res and pump and getting a smaller one
