  I google'd slipstream.  It is interesting.  There are MS suggested 
methods, as well, for the SPs anyway.  Creating an updated WinXP install 
source and an automated install method are definitely on the list.

  I'm enamoured of Dell's 3 year, next business day, on-site repair. 
Included as a minimum on their Optiplex's; extendable to 5 or more years.  I 
get a pretty low failure rate, too.
  Sometimes if you buy 50 of an item, you might get 3 different revisions 
requiring completely different drivers.  I've been bitten by this type of 
thing before.
  If you buy in low quantities and you have time to support the equipment, 
by all means, get whatever costs less.  I've had the staff in my dept 
reduced by 66% (there were 3, now there's me).  Whatever work I can avoid 
helps make it possible to sleep and visit my family...  ;)

  Memory overcommit is very interesting.  I'd be willing to try it on VMs 
that aren't active all of the time or as a way to give each VM access to 
more memory, in case they happen to run a memory intensive app occasionally. 
I wouldn't want to have 20 people complain about speed because I don't have 
enough physical RAM and have management kill the project because they've 
decided the concept isn't feasible.  Maybe once the concept/system is 
accepted I could push the envelope a bit more.
