There are ways around this like using radiator fluid instead of water, or using special non porous tubing however it really isn't practical.
A t fitting, foot of tubing, and a cap won't run you more than 5 bucks.
Read up on water cooling before you consider it because you don't seem to know all that much about it yet.
Fill your t-line up all the way maybe...
i was assuming the bucket would also serve the purpose of a reservoir, not just the T-line and fillport, that's why it was 50 (it was actually meant to be $40... but you get the point).
I know tubing is porous, but in this setup, evaporation through the tubing pales in comparison to evaporation in the bucket, which won't be that staggering anyways (i live in Australia and i left a big rubbermaid container with a surface area of about half a square metre filled with water out in the sun one day last week at about 35°C and less than 2 inches had evaporated after 10 hours in full sun)... but seriously, when you've got a bucket sitting there, how hard is it to whack another pitcher of coolant in
so, the way i figure, the main issue is gonna be microbial growth and hindered thermal conductivity caused by dissolved gases and airborne minerals (mind you its not gonna be hindered too much either, so the bacteria is the main issue)
also, you're never gonna be able to completely fill your T-line... so just try to make sure its above the rest of the components (air is lighter than water, after all)
EDIT: oh yeah... you can fight the bacteria problem by adding a slash of denatured alcohol occasionally... it'll lower the thermal conductivity, but it'll kill the bacteria quicksmart... probably worth the tradeoff if you wanna run a loop like that
