11 days is super fast indeed.
what are your thoughts on this for the grill? there are a lot of computer fan grills at amazon, or any store, that could work. the first one i liked has some sort of botton in the middle, that would be the only con.
most of them look like this:
and they go as cheap as 1 dollar each, check out this beauty (but its 80 mm diameter), the grados should be between 40 and 50 mm. that is 3.1; 1.5 and 1.9 inches aprox. respectively.
Thanks for your suggestions. I've seen some custom mods done with the computer fan grills during my travels. I have a Micro Center in my area (major computer store with a huge DIY section) and they have many mods available. I wouldn't have to pay shipping. Next week, I'll stop in and see what options exist. Thanks again.
