If I go 3/8" or 1/2" I will make EVERYTHING in the system be native to that size. Now, I did post earlier that there were parts in 3/8" sizes that aren't made in 1/2" sizes and heres why: for my senior project next year I plan on building a case from scratch (aluminum angles, bars, sheets and tubing all riveted) and I've already run into space issues. I'm attempting to keep the case as small as possible (was origionaly M-ATX spec) but still fit ATX mobos and Fit a BIX2 up front. So, as of now its a normal vertical tower thats 16.5"Lx16.5"Hx7.5" (modeling it out in SketchUp, will post some pics soon), theres easily enough space for 2 5.25s (will fit 3, but I need to relocate some hardware to fit in the third) but theres no space for the res or the pump unless I put them on the bottom of the case (in the middle of the intake flow and in the way of the PCI cards) or suspend them in air (which I don't want to do, I want this to look clean and professional). If the third 5.25" bay will fit: I can add a res into that bay (the other two are taken up by a DVD-RW and a HDD Cooler cuz theres no HDD cage) and just find out where to mount the pump (which will get tricky if I want to keep the middle of my case from being clogged with tubing). It was after I got this idea that I came across this:

Yeah yeah, I know its a Koolance and its overpriced; but its is SOOO cool looking and it does exactly what I need it to do which was find a place to put my pump and res so they're completely out of the way. However, this product is only available with 1/4" and 3/8" ID barbs. I went looking for something like it with 1/2" ID barbs, but found nothing. So this brings me back to my origional question: if i got that Koolance thing with all 3/8" ID-barbed water blocks, would there be much of a difference from a 1/2" ID setup all the way around?
