Thanks for the input!
Now I can refine my questions a little bit more.
12) I heard a lot of people telling me that the Eheim 1250 pumps are pretty good. How big is it exactly (or approximately)?
13) Is there any significant difference between the Black Ice II and the AquaCoil II (price, size, performance)?
14) Is there ANY disadvantage to having the pump turn on at same time as computer (pump relayed to PSU)?
Clarification: If I had the pump connected to an external switch, then I could turn on the pump before I turn on the computer. Is this better/no difference/worse?
15) Is a big reservoir tank necessary or is a little on (say 4" x 4" x 2") okay?
16) Since I won't be putting an HSF on the waterblock, what kind of water block should I get (I want to use the 4 motherboard mountings instead of the socket clips; using an AMD MP)?
17) Assuming I use the Aquacoil II Radiators, would there be any adverse effects (noise, heat, etc...) if I stacked one on top of the other (space constraints)?
18) How do I make a shroud?
18a) Where can I get sheet metal for the shroud and ducting?
19) Where can I buy no spill couplers for the tubing?
Thanks for the previous input. I hope you guys can help me out on the new questions! Thank you!
