Steve,

I am waiting for the updated quote. I am assuming you are waiting for
Julien to confirm?

Are both machines dual socket?
Is there a price difference between the R150-T61 (4 x 3.5" bays) and
R150-T60 (10 x 2.5" bays)?
I believe ultimately, we don't care about whether the machine has 4 x 3.5"
HDD/SSD bays or 10 x 2.5" HDD/SSD bays.
So we should go for the version which is
A) either cheaper
B) available more quickly

@Julien, can you confirm?

That would be great

From my perspective everything is ready now, pending is an updated quote
I will ping Julien separately today to make sure he agrees

Best Regards
