In that case, 8 ft sounds like a good extra. I would go with 10 ft, but the Tygon is very expensive.
How co I connect the tubing together? Would I need one of these dealios: Adjustable Plastic Hose Clamps
? If so, think they have these available at Home Depot? Perhaps one of these: http://www.homedepot.com/prel80/HDUS...4+3116&pos=n06
How often do you replace the tubing (if at all)? I'll definitely be saving any extra Tygon for a future check on the loop should I have to replace any tubing.
Ya'll know I have that ridiculously huge case. So my motherboard is at the very bottom. You can imagine how far the T-line will be. The T-line will be a bit less that 2 ft alone!
Nubius got it a bit easy there, eh? Your T-line is like 6 inches from your CPU! Look what I have to deal with:
The red-line gap is 2 ft. I'll probably end up connecting the T-line through the blue lines right after it cooles the GPU, so maybe half the distance.
I've even been having trouble trying to plan it out, despite it being such a massive case. I was thinking of putting the heatercore to the left there, but that would defeat the purpose of that left 120mm fan & 80mm intakes. It would just blow air right into the heatercore when I will have 2x120mm on it anyway. I guess it wouldn't hurt. That 120mm exhaust to the right is the only one pulling air out.
Speaking of fans (sorry to drift off-topic), should I arrange my 2x120mm on the heatercore to push air ONTO it or pull air AWAY from it?
As for messes, you should see my case. And I don't even have WC yet! That's what a massive case will do to you: place the PSU as far as possible from the mobo so everything is a damn stretch.
