We are running a Cyrus murder with 2 frontends, 2 backends, and 1 mupdate 
master for approximately 30,000 users (although actual usage varies 
greatly).  The frontends and mupdate master are Dell 2850s with dual 3GHz 
Intel Xeons.  In general, the frontends and mupdate master are pretty 
bored.  You can view the performance graphs for these servers at:


These servers have Dell's hardware mirroring for 2 internal drives, which 
seems to be more than sufficient.  I'm a big fan of dual-core and/or 
dual-cpu solutions regardless of the size of the server.  Usually the 
price difference is negligible.  Personally, I would buy the new low-power 
Intel Xeons or AMD Opterons if I were purchasing these servers today.
