I took some of your guys advice and added some 90's. i have to say I'm glad i did it changed the whole look and cleaned it up a little also added some new front panel goodies.
This next pic the tube that runs from the left port on the motherboard block will be removed soon. but first i need to grab me one more pmp450s pump for a duel loop. The CPU and vrm's will be on one loop using the top rad. and the motherboard block and the cards will be on the other loop using the bottom 240 rad.
Ill have a tube running from the right port on the motherboard block to the res on the front of the case. i don't think i will like the look of a tube running from the front of the case to the motherboard block. I thought of running the loop from the top card, into the motherboard block, out of the motherboard block, back into the top card. However i'm not sure what that will do for good flow through the card blocks.
