Been to the gym lately? If not, then let this be your new motivation. What we're looking at here is a purportedly forthcoming Xbox 360 motherboard redesign that takes aim at slimming down the portly figure of Microsoft's console. Sure, there's a small chance that this diet could be the work of a scarily talented console modder, but it'd still be a near-impossible task to work in what appears to be a CPU / GPU combo chip (pictured after the break) under that greatly reduced heatsink. Note that there's also an extra SATA port at the top left corner. Perhaps this is the "Valhalla" revision that we've all been waiting for? On a related note, Microsoft is currently hiring a Motherboard Design Engineer for the Xbox 360 Console Development team, with such saucy tasks as "specifying, designing, implementing and verifying the mother-board and other various sub-system boards that make up the XBOX 360 product line." Feel free to sign up if you think you can hack out a better motherboard.
