    Ya, it would be more authentic but the filament supply
would then
 weigh 20 lbs instead of 2. 
 And why is this a problem? It's hardly going to be a portable device,

 Tony, your reasoning sounds like what IBM uses to decide how much 
 something should weigh. 
You've still not explained why this is a problem.

I really don't understand this modern love with making things as small 
and light as possile. I'd rather have things that are heavy enough to 
stay put (in the case of a rack unit, not to topple, or even feel wobbly 
when units are extended ot the maintenance position) and that are large 
enough for me to be able to work on them.
