Water cooling advice

I want to water cool my next pc to keep it cool and not pay outrageous money. and also the noise of 8 fans going on a pc Is driving me crazy . I want to practice water cooling with my athlon pc by rebuilding that bad boy after I killed it. I put new thermal paste on theen started her up and and the screen was blank. now I use a ibm think center with one fan in the back and a tiny rudy poo heatsink. and honestly the 60 c temps idle scare me on this thing. at load my temps shoot up to 70c. not only that but it's a intel celeron d and it's unning at stock speed. luckily this is only a temporary replacement until i build my new joint. but any way I wanted to know if my idea was practical. I am one of those guys who say doing is worth over doing. I wanted to use a giant truck radiator two big 12v fans and a high flow pump. . This is a wild overkill design I know but how pratical is it? also if anyone has any comments on my other issues I have alot I hope there's no posting limit on this site because I have three computer projects happening at once and theres a roadblock for all of them

Thanks in advance
