Hi again, it's been a while since my last post as I've had very little time for modding. This post should have been posted yesterday and there is another one from today coming in an hour or so (yeah, I type slow). I've always liked Zalman's series of coolers but never really liked the blue color so I decided to do some experiments on removing the anodized layer. I went to the store and bought some sodium hydroxide, something most people use to clean their drains without knowing it'll eat aluminum for breakfast if given the chance. Sodium hydroxide is VERY corrosive and while I still got all my fingers left I'm not going to recommend anyone trying this at home. (And if you do, wear protective glasses, PVC gloves and make sure you're in a well ventilated space (read outside)). I used two old glass jars, one for the sodium hydroxide and one with filled with water used for stopping the corrosion. Once you mix sodium hydroxide with water it'll react strongly and produce lots of heat, to limit the reaction always use warm water. When you drop the aluminum in the sodium hydroxide it'll sit there for a second or two and then start to dissolve. The whole process is very quick and since I only wanted to remove the top layer of aluminum oxide I took it out after about 10 seconds. I don't have many pictures of actually doing anything as I was pretty busy trying to avoid damaging the memcoolers (and myself). Anyways, here's the before and after shot: And here's the whole set. It looks a lot better with bare aluminum in my opinion and when I get the chance I'll do my Zalman northbridge cooler as well (and if I have the guts, my iPod mini ). I also cut a more manageable piece out of my large sheet of 1/2" red UV plexi. I'll use this plexi for a lot of details inside the case and I'm doing some tests with these pieces. The idea is to make something to hold the Tygon hoses in place but I'll get back to this in a later post.
