What are those holes for?

I am wondering what are those round holes between screws made for. Should I move X-Y steppers to the outside so they will not overheat if I will mount side panels to my M200?

This is v.01 model or v.02?

Why did you guys eliminate these "cooling holes" from V02?

In fact, motors cannot be moved to the outside of the printer because motor shafts are a little too short. ;)

Once again.. I'm thinking they are for weight reduction..V1 looks like Swiss cheese... It's obvious the V2 is now heavier than V1.. Please take caution when lifting the V2. Lift with your legs, not your back... :D
