Just make sure /home is on fast SCSI drives in RAID 1, 5, or 10.  
Actually, the box with NFS /home and NIS/LDAP doesn't need too much  
horsepower in terms of RAM or CPU. 1-2 GB of RAM and a standard  
Athlon 64 ought to be more than enough, unless you have a gigantic  
setup. It's going to be primarily disk and network bound. All the  
servers need GIGEthernet.  The LTSP servers (not the NFS/NIS machine)  
can get by with software RAID 1 on IDE/SATA disks (you don't even  
really need 10k rpm drives here, save that money and spend it on more  
RAM). Here you want dual core/ dual processor and lots of RAM. It's  
basically an app server. Users aren't writing to the actual disks  
here, the only writing is happening in /var in the temp files and logs.
