I also have a few other general question, some have to do with the waterblock, some with general watercooling, so I'll post them all here and all at the other site, and see which answers I can get.
1. Right now I'm looking at some threaded fittings. They fit into my design quite well, but they're only 3/8" ID because they're intended for high pressure, but I can bore out the inside of them to be almost exactly 1/2", since there'll be almost no pressure in my system. The only problem is that if I bore them out, it exposes the plain aluminum (since they're anodized or whatever). Would that be alright (since it's only on the inside, or should I keep it at 3/8" or not use 'em all? Also, if I do bore them out, should I do that only to the middle one, since you can't put double the volume out than in anyway?
2. Is glycol alright to use as corrosive inhibitor?
3. Can I make the top 2 pieces of my waterblock (that are not used for transferring heat) out of aluminum, as long as I protect the outside from corrosion? Would it be a problem on the inside? I don't see why, considering my dad's truck has an all aluminum heatercore, and it's perfectly clean (Glycol in the system).
4. Also on aluminum, does tubing made out of it work? I could get some thin-walled stuff that would work pretty good... again on the corrosion.
5. Do I have to make a backplate for my waterblock (To mount on motherboard)?
I'll edit this post if I have any more questions!

5/8" wide is fine, just make it thin.
1) Don't use exposed aluminum with copper, especially in contact. That causes an electrical connection and all hell breaks loose on corrosion. You can get 3/8" Brass barbs at a hardware store and bore them out somewhat. Would be much better (as long as the top is brass, copper or plastic).
2) I just use antifreeze. Pretty sure glycol is in it.
3) Not if the base is copper. The outsode of the block is of no concern, it is the inside were the water is that causes the corrosion. Aluminum on copper is a no no.
4) Same as above. Not sure what you want to use metal tubing for anyway?
5) Only if the block is very heavy. I don't see your as being heavy enough to worry about. However it wouldn't hurt. That can be made from aluminum.
