Just to throw my 2 cents worth into these discussions, I've recently taken 
delivery of 34 of the following machines, so around 200 TB total usable 
storage.  Cost is $6.7k each, so about $1200 per Terabyte.

The local disks exceed 200 MB/sec read/write speeds.  As NFS servers we 
can get about 100 MB/sec via one network port of 160 MB/sec via two ports 
in each box.

SuperMicro H8SSL-i motherboard

AMD Opteron 175 processor

2GB unbuffered ECC DDR-400 RAM in 2x1GB (Kingston KVR400X72C3A/1G)

AOC-LPIPMI-LANG IPMI card

AIC 16-bay hot swap SATA chassis with 3 hot swap power supplies 450W

16 x 400GB Western Digital RE2 disk drives

ARECA 1160 disk controller configured as RAID 6 with 14 + 2 and no hot 
spares. The disk controller is configured with one 16-disk RAID-6 set, and 
two logical volumes.  The first logical volume (20GB) hosts the OS, and 
the second logical volume (remaining disk space) is for data storage.
