aren't blades still a significant premium?

well, nothing beats the incremental expandability of a stack of 
separate boxes.  given that modern cpus are drastically cooler 
(esp per flop) than even 2 years ago, fans rarely run fast.

a blade chassis usually requires power other than the usual 15A circuit;
nothing custom of course (L6-30 is my favorite) but something like a 
dual-board supermicro 1U is pretty convenient and flexible.

if office, I'd certainly just get minitowers.  but I wouldn't consider 
putting more than a few in an office, since a ~250W minitower already
corresponds to the power dissipation of two people...
