Yeah, the tube was kinking. I'm not really impressed by home-depot's clear vinyl tubing... kinks way too easily. This project was just purely to get the heat and noise away from me when i'm play WoW or D3 or HL2. I still have the system OCed, just a bit.
As far as brands, most of it is custom fabricated. The water blocks i purchased of some dude on ebay about 6 years ago. All of these parts came from my old setup.. back when I was 17 and was aiming for extreme dual TEC + water cooling on my dual celeron Abit BP6 setup.
The pump really used to kick ass, it had a head of 20+ ft. but now barely made it past 3 ft. The flow rate was rated at 500gal/hour but now I'm lucky if I see anything more than a trickle. I even took it apart and tried cleaning it; not much improvement. But it gets the job done.
This is what I get for spending ALL my extra cash on my ride and nada on my rig. 6 years ago, it was the other way around.
Next year when the cash comes in from the new job, I'll build a dual independant cycle system that will work with an array of water blocks and peltiers, something extreme tha will require an anti-freezing agent in one of the cycles.
Yes, this isn't very practicle for LAN parties, unless I host them! hehehe
ohh yeah, here are the OC results. Nothing too impressive, but its rock stable and its not bad for not using the TEC's right on the CPU/GPU.

Base Mhz:
CPU: 3.2ghz --> 3.6 = 12.5% gain
RAM: 200mhz --> 225mhz = 12.5% gain
GPU: 390mhz --> 514mhz = 31.8% gain
RAM: 700mhz --> 923mhz = 31.9% gain
One more note: next time I get a water block on the mobo chipset. Very important.
