Overkill, yes, but we're trying to compensate for the poor performance of the block here. This could be a good lesson: an Alu block for $15-$20 and a pump for $25 might turn out to be almost as good as an Eheim 1048 $60 and a Maze 3 $45.
Also, keep in mind that a 600gph pump won't get you an effective flow that's anywhere near that, especially the Rio, because they have a small head, compared to a lot of other pumps. I think he'd be lucky to get above 100 gph effective, but that's what we're shooting for here.
The 1/2 in. would be a good upgrade.
I also suspect that the HC is copper inside.
I have to say something here about what started all this: Unaclocker's article.
Una started this by putting this article together. Is it good? Well, he might have emphasized the need for lapping that Alu block, and state clearly what kind of results one can expect, but he didn't. I believe that this setup can work, that spending an extra $10-$20 on a more powerful pump would have made a big difference, but all in all, the purpose of it is to get someone to be watercooled, not to give anyone the ability to get into some serious overclocking or anything like that, for a relatively low price.
As most of us know, Una is not here anymore.
