Well, I only box 6 myself but my buddy boxes 16 regularly and I've seen him handle 24 or more when guildies have had to leave raids early. When I add a new PC in May, I want it to be able to handle 5 so I can increase my boxed accounts to about 10. I'll reduce my oldest PC from 2 to 1 box then since it only has 1.5 gigs of memory and a 256MB video card. It seems to strain some with 2 right now even with all models off as its only a P4 2.4 but its the only one with 2 monitors at the moment...21" CRT and 19" LCD so I can at least see the views of both boxes it runs.
