I won't comment on Dell in particular beyond: I've worked for
competitors, am not terribly impressed with their HW or price points,
and see little advantage over commodity off-the-shelf generic x86
hardware).  Ditto for Compaq, HP, IBM, etc.  That all said an approach
I've been wanting to play with is various equivalents to a blade box --
either directly using one of the off-the-shelf blade systems, or a rack
full of (say) ITX motherboards, 4 per U, all sitting on a CAT5 copper
Gig-E cross-connect with an ultra light weight messaging layer... With a
little work node cost can come in under $700 each (4G RAM per node, 2GHz
P4, etc, dropping down to $300 for lower specs), and then $$K for the
switch.  If you can sufficiently loosely couple your server architecture
for your game definition and keep your flash crowd/working set
collisions down so your backing store doesn't go insane it could make a
pretty interesting approach.  The early problem you run into there is
how very slow PCI is.
