As much of everything as you can afford. :) The build isn't heavy in any particular metric, so don't sacrifice RAM for SSDs for example. RAID 0 over SSD would be nice and fast, but I prefer having a good amount of RAM and a tuned ext4 (no journal, long commit delay) so data doesn't actually hit the disk as frequently. Keeping the actual build directories on a separate disk is good for performance and not causing data loss when you lose a disk. There are people that have 64GB in machines and then set TMPDIR to a tmpfs. Surprisingly this isn't that much faster (5% or so), but it's a lot easier on the hardware and power consumption.
