Cheers guys, it took a fair bit of mixing to get the pastel yellow more of an MSI yellow.
I'm using a couple of XSPS lcd sensors, one in the res, and the other isjust above the top gpu, for an air reading. for the basic temps it is core temp.
The 2 tubes just makes it look pretty, it's called running them in parallel, there is a lot of debate if it helps or hinders preasure and flow, but I have tried it both ways, and for me it works.
The optical bays have gone mate, it looked too cramped once the res was on the bracket . I've got an idea brewing for something special for the empty space.
