	In our case we chose DS10 machines because of their better memory
	performance compared to UP2000.

	This is true. In our case Compaq seemed to be much more 
	interested in selling DS10 models instead of their slim versions.
	I suppose they can get more money by selling slim models to commercial sector
	and standard models (DS10) to universities.
	Another thing to keep in mind is the heat.
	I don't know what is the situation today, but I have
	heard that Compaq used to have somekind of heat problems with
	fully loaded DS10L racks. 
	in addition, I do not know if Compaq even has 
	DS10L version of their fastest DS10 models.
