Thats almost the pump and restop I use. I use the 18 watt 3.2 pump. The old 10 watt isn't used much anymore, but it should suffice. One reason they made the 18 watt version is the old 10 watt had impeller issues. Can't remember what color impeller is the more modern one, so thats up to you. I'd just go with the DDC 3.2 aka the MCP 355.
In a week or so you'll start to understand it. Give your self time. It's your stuff, your knowledge and effort to figure it out is up to you. You still need to learn about building and maintaining a loop.
Took me 2 months before building a parts list, read four top forums every day every recent post about watercooling, and another month before I bought my parts. So it takes time. No rush, it's a hobby.
Well I've got about a month before I have the money for it all. So hopefully thats enough time for me to learn about watercooling in general, building a loop, what i should be looking for when choosing the parts and also maintaining the loop once ive built it.
If I don't think I know all that after a month then I'll just hold it off, until I do know all that I need too.
Oh and thanks for answering my question about the barbs and tubing, It was doing my head in haha.
OMG? Please read the other forums a LOT, mainly OC Forums, and read a lot. Some good stickies there too. And the guides I linked you to.
It's best to ask questions at a more informed forum. This place is kinda lacking in watercoolers. We have a few good ones, but OC Forums has 20-30+, and about 10 of them help on a regular basis. I'm Conumdrum there too.
