I am not a huge fan of steampunk. I like the attention to detail that I see in some of the products and the overall cool factor. I would never use a steampunk product though, I like my tech to look high tech.
If you like steampunk gear, but aren't able to build your own you can buy this interesting steampunk flash drive. The drive is made from real wood along with lots of brass and a small gauge.
The brass tank looking cap on the top covers the USB port. The style of this thing is more important than capacity, I am not even sure how much storage the thing has. If you want it, you can pick it up for $300.
