We just bought our cluster from a vendor (Western Scientific).
I would recommend going to a vendor if you can afford it, mostly
to guarantee there won't be any hardware incompatibilities that
are sometimes hard to work out until you start setting everything up.
Hardware Linux vendors will also quite possibly be more up to date
on what the best configurations/tools might be.
Price it out and take a look at the relative costs of going the "do it
yourself" route and from a vendor. (In our case, our prices were pretty
competitive w/ buying cheap 1U dual xeon blades from bulk hardware
companies like www.mwave.com and the support is absolutely brilliant).
If it looks like it is much cheaper going the do it yourself route,
take a look at the following:
Oscar will automate installation over a network and make it reasonably
straightforward to install over an arbitrary number of nodes, setup a
reasonable queueing system, install mpi(ch), take care of user accounts
and maintain patches/updates. The documentation provides some good advice
on "reasonable" configurations as well.
Read over the "quick install" to get a sense of the work involved
setting up a cluster on your own. Its quite impressive how straightforward
this stuff has become. There is no 6 node limit :)
