A pc you can ride:2011 HAF X mini bike
You may not get very far on this ‘Pocket Bike’ / Mini Bike largely because of its ride comfort and the amount of fuel it can hold but the HAF X Mini Bike is certainly one astonishing PC case mod.
Though the bike itself doesn’t house a display, you probably don’t want to be doing that while you’re scootering about.
The idea itself sounds great, why go to work or your mates with a memory stick when you can get there with your own PC and just hook up a display?
