Definitely heavy as a neutron star! TBH, the coolest looking one (to me at least) is/was Indigo 2. Both green and purple one! They ARE more manageable.

As an indigo^2 user: holy shit they were trinitron heavy, too. But the internals of that case were [stunningly beautiful](http://www.futuretech.blinkenlights.nl/i2/i2open.jpg).

All SGI hardware was beautiful inside (pun not intended). Source: was SGI employee for some years.

I have a late-model Indigo2. They're definitely a lot heavier than they look. The later models also suffer from being a bit of a "bridge" machine. Newer CPU and graphics paired with older SCSI, Memory, and Networking.
