First off, thanks for the informative responses.
1) You can get O-rings at WASDKeyboards. I wrote a review on them if you wanted to get some of my thoughts on them. You can also order a sampler pack from WASD which would allow you to try out some o-rings before you bought them.
All of the WASD O-Rings are tiny, in fact his last announcement about them is they have a newer smaller one. (Doh!) This is the opposite of what I am looking for, my brother bought a pack of the thickest ones, and you cant really feel the difference, but the sound dampening is there. I thought about double stacking
, but then I'm paying at least double... so might be better to buy in bulk. Ive found that mcmaster.com seems to only offer 70A and harder orings. The cheap stuff seems to be made out of nitrate, the better stuff out of silicone, or perhaps EDPM rubber.
2) I don't know enough about soldering LEDs to answer
This is a fustrating subject, it seems like all the reviews I've read simply get the keyboard, keep it, and copy paste the same review over and over again. The most "daring" reviewers will remove a key or two to show off the LED with no specs at all. Most say just look for the actual size. (3mm, 5mm, etc etc) The best review I could find is this one: tweaktown.com
I am reasonably certain I have 3mm sized red leds. I found some nice 3mm's here
. Not sure if I want to resolder a bunch of stuff to experiment just yet.
3) Yes keycaps can be bought that are lower profile. The CM Storm Trigger has CM's OEM profile. You'll probably want to look for a Cherry profile or a Leopold OEM profile. Many group buys from Signature Plastics have a Cherry imitation profile. Besides that, I believe imsto's keycap sets are Cherry profile. Or you can buy an old Cherry keyboard for just the keycaps. You can check the GB section or classifieds for pricing. I'm no long sure what "expensive" means to most people anymore
This seems very complicated, with people in the "know" saying it's common sense, OEMS
a "common" that alot of keyboard makers make. (Including coolermaster.) Another factor is that there are some makers who use different sized keys for different parts of their keyboard, and/or poorer quality keys that do not fit, or have uneasy leveling like they are using damaged molds. I guess I will need to find out the exact dimensions of a OEM Key. As far as price range. I have no clue. I would think $20-25 is a good price range. There are exactly 109 keys on my board. The more duh, is that smaller keycaps would make me use smaller sized o-rings. So I might just want to leave it at OEM key size.
