I did the same thing and am considering the same case. Thanks for the pics, it's nice to see what it looks like in reality. Personally it seems long enough. They do make usb extension cables in white for those times when you need more room. Monoprice has them for under 2 bucks:

Probably can find them on ebay for even less.
