I filled the loop with Mayhem's Pastel Mint Green. I like it but it's a tad too light for me - I was looking for something a little bit darker...hmmm...will work on that later. And here's how it looks with the white LED's in all of the blocks Now while I was taking those last pics I noticed this side of the 5.25" drive bays was in need of something so I made up a cover panel out of black acrylic to make it look better. Then I decided that the translucent green accents inside weren't as lit up as I'd like from the white LED's so I decided to add a pair of UV LED strips to either side of the top window. It worked but it had the side effect of making the Mayhem's Pastel Mint Green look almost white :O
So back to the light green issue...I had a bottle of Primochill UV Brite Green dye so I decided to squirt a bunch in - I ended up using just about the entire bottle (which dyes a gallon of coolant) but it turned out perfect and now the UV LED's actually make it light up green instead of turn a pasty white color And with the top panel on and UV LED's on: I like the way the UV LED's light up the top panel etchings purple as well - it sets it off nicely. Next update will be the final update with the final pics!
