I have 168 32-bit machines (IBM HS20 blades) which can take 8GB RAM
each, although we don't have them configured with that much. So there
are plenty of these machines available.
I tend to agree though, that for MySQL, if you want lots of memory its
better to go for a 64-bit platform. We've been using Alphas and Tru64
for MySQL databases for years.
