It depends on whether or not you want to do many short simulations or a
few big ones. In the first case single processor nodes will be fine,
otherwise you want more processors per box. Dual nodes probably offer
best price/performance, but I just ordered some Quad boxes for exactly
these very big and/or long simulations.
You should also consider what OS you want to run, and get stuff that is
supported. We are using rocks (www.rocksclusters.org) which does not
have very good support for e.g. SATA disks.
