In another thread over at hardocp I did a description of costs for a full water- cooling system with pump and bong for about .... $35. For another few dollars you can even add a brass or copper vid-cooler. I will just copy this info over to this thread:
Read both my articles, they really are meant to be read together:

Check at different hardware stores and start pricing this stuff out. Home Depot is not always the best place
The water block is about $12, or less. I said less than $20 in the article, because I was including the cost of my 2 vid card water blocks which are about $2.50 each.
The copper cap for the waterblock is about $6.50 and the three copper hose connectors are about $.50 each. Rivets for fins add less than $1. Somebody should cut you a 2.5 x 3.5 inch peice of plexiglas for under $3. I think they charged me $2, which brings us up to $11
The bong is about $3 because you should be able to find a spare 5 gallaon bucket for free. I am asuming this guy already has a case fan, even a cheap generic one will do...the showerhead I used goes for $2-3
For the cheap pumps you could try this:

I would prefer a Danner. I found this in about 30 seconds, the 140 gph model is $19.99 at this link :

I use the 190 gph model and it seems fine. I think it was $20 locally. Some of these big pumps are overkill. If you can increase the efficency of your shower head you can go with a less powerful pump.
I am sure you could find a better deal on a pump if you looked. I remember somebody posted some really good deals on slightly larger Danners for about $18.
I did not mention the hose, but its really cheap. I think I spent around $1 on mine. I think its about 25-35 cents a foot. Plan well and the cost should be minimal.
That seems to add up to around $35.
I just got an axia and have made some new vid-blocks. I will put it all together soon and post the results
