1: The machine is larger than your fridge. Despite this, it does not keep your Coke cooler.

2: The power supply is bigger and louder than the engine in your brand new sports car and/or jet plane.

3: It has "Cray" spelt along the side of it.

4: You don't manage to successfully plug it into the normal 220V electric socket in your bedroom (doh!).

5: The liquid-based cooling system sounds like it could freeze the Sun.

6: It has nice LEDs on the front which are supposed to tell you some information about the CPUs but you have not noticed any correlation between what you do on the machine and how the LEDs blink.

7: You try to turn the machine off, but there's no ON/OFF switch.

8: You try turning it off by pulling the plug out the wall but it merrily continues going as if nothing happened.

9: It has more memory than the average user has harddrive space altogether.
