Bricasti Model 1 Series II DAC

I had my M1se with network / renderer card upgraded to an S2.  I think the actual upgrade, excluding shipping, took a couple of days.  Cost was $2500 plus shipping. 

I seem to be missing something. The M1 Series II is housed in a larger chassis from the previous version. 

If endusers are getting upgrades to the Series II upgrade level what's missing?

From Bricasti 

"The M1S2 is focused on simplicity of design and includes a host of new performance milestones including our latest MDx processor, new higher current twin linear power supplies with larger performance capacitors, all fit into a handcrafted chassis milled from solid aluminum that stands taller in size fitted with the same M1SE feet as standard."

It seems the capacitors is the reason to add vertical real estate. How is this implemented with older chassis?

I have not unpacked my M1Series II yet as I'm building a room but need to open the hood and see the caps to make sense of this. 
 

You get a new chassis with the upgrade. 

That is the first I've heard this and now I understand.

Thanks. 

I just received my M1 S2 DAC that was upgraded from a M1SE.  It’s really like getting a brand new DAC.  It has the new multicolor display and remote control (I didn’t have a remote with my M1SE).  It sounds great out of the box but I think it should get even better with burn-in.  I’m very happy with Bricasti’s service and making this upgrade possible!
