Not quite sure what this is, but it looks like it is a dial overclocking thingy (technical term). Wish I could read Japanese, cause if it is what it looks like, I'd wanna get my hands on one for sure..... If any one can translate what is on the site please let me know what this "turbo controller" actually does. Update: Found a few sites that show you what the thing does. If I get this right, the unit is hardwired into the motherboard and allows you to change the FSB speed among two or three other variables. Scary, but cool.
