I'm finally about done with my wc setup. Easily dropped over $400 into it. I went all DD parts including TDX Block, 6800 Block, 12v Pump, fillport, and BIXII. Tubing is mostly Tygon. I understand I could have gone with components that were cheaper and perform as well/better, but for my first project I am totally happy with the parts I chose. The only part I'm not that proud of is the use of zip ties to mount the 120mm fans to the grill and rad, but it was just so much easier than trying to get up in there with nuts and bolts. Couple mistakes I made were two misplaced drill holes in top of case (have black tape covering it up for now) and I didn't use anti-corrosive agent when I tested for leaks. Few days later when I went to install the blocks for real there was some corrosion already. All my decisions were made from info I found on this board so thanks [H].
