swiftech apogee and ambient temps

Well.. even with my pukey pump and rad.. i installed the apogee. I must say.. even with the house at 80f it stayed at around 43c at load.. now with the a/c fixed its staying at 37c in game with ts up and browsing the net.. not bad if I do say so myself. I did do it right this time.. I didnt funky rig it..lol
I also found something cool at lowes building supplies. It's a compression shut off valve. I looked on thier website but can find it. If I do I'll post it. I ran it for 6 hours on test.. not one leak. For $6 (not including the apogee) I dropped my temps becuase of reading and taking my time. I likey! No I wont post a pic until I have it all done right.. When I get my pump.. new rez and my new rad.. then I'll post.. cause I still have some planning to do.

I do have one question. Does brass mix with copper in the wc set up? I'm not using any. But I thought about it. I used plastic instead. I didnt know if it would have an effect on it or not. I'm runnin distilled 90%/antifreeze 10%. Just to let you know.

I refuse to answer w/o some pics first

Brass is a copper alloy, so you're golden.

Cool so that means I can use them without the worry of breaking the plastic ones while putting the hose on. Cuase I found some seriously cool looking barbs at Lowes.. I searched thier site again.. and nothing. I'll have to post pics of them instead.
