I'll be kitting out a Cosmos II in the next few days. I've had to give up on Cooler Master's fans - I live in the UK and I can't find them here or anywhere else. They're on sites for sale, it's just that no-one seems to have any. I decided to get some of these http://www.enermax.com/home.php?fn=eng/ ... 1=13&no=31 instead - they have a toggle microswitch for the LED control but I figure if I hack those off and replace them with suitable 2-pin connectors, I'll be sorted. I'll let you know how well it worked after I've put it together over the weekend. Sorry CM - I'd have bought yours, but there just weren't any of them around when I needed them.
