I goto Louisiana State University
We have about 32,000~40,000 students so we not only have alot of computers, but diverse labs as well.
As far as I can tell the mac labs are all (or were , I don't frequent them, tagged along with a friend) IMACS with external superdisk drives.
Here the poop on the rest from our CS dept webpage
"The DEC (Compaq) Alpha Network (Telnet to server)
The DEC Alpha network consists of two 500 MHZ DEC Alpha servers, with 0.5GB of RAM and 2MB of cache each, and 42GB of total disk space. Served by these servers are 15 433MHz DEC Alpha workstations, each with 128MB of RAM, 4.3GB of disk space, and 17" trinitron color monitors. All servers and workstations are running the Digital UNIX 4.0D (Tru64) operating system with the Common Desktop Environment (CDE) Graphical User Interface (GUI), and are used as the main backbone of the department for research, education, Internet, e-mail, etc. Most of the workstations are housed in the Graduate Students Laboratory in 256 Coates, and in faculty offices.

The SUN UltraSPARC Network (Telnet to server)
The SUN network consists of a SUN Enterprise E450 server and 20 SUN Ultra 5 workstations. The server has two 300MHz UltraSPARC II processors, each with 2MB of cache, and a total of 512MB of RAM and 28GB of disk storage. The Ultra 5 workstations each consists of a 270MHz UltraSPARC IIi processor, 64/128 MB of RAM, 17" color monitors, and 4.3 GB of local disk space. The SUN workstations and servers are running the Solaris 2.6 operating system with CDE. They are mainly used to support Computer Science classes, currently with an average of over 1900 accounts installed per semester. The SUN workstations are housed mainly in the UNIX Laboraroty in 167 Coates.

The Microcomputer Laboratory
The department also has a microcomputer laboratory consisting of 20 Dell Precision Workstations, and one server, all running the Windows 2000 operating system. The workstations have a Pentium IV 1.4GHz processor with 256MB RAM and 17" Trinitron monitors. The server has two-1GHz Pentim III processors, 1GB RAM and 80GB of SCSI storage. The lab is used mostly for teaching introductory Computer Science classes, and for general use by Computer Science and other LSU students. Funding for the lab was secured by a grant proposal written by Dr. Elias G. Khalaf to the Technology Fee Committee at LSU. The lab was set up in the summer of 2001.

A Cluster of Workstations
In the fall of 2000, the department completed the setup of a cluster of 24 733MHz AMD Athlon PCs running RedHat Linux, all connected via a 100Mbps Ethernet switch, in turn connected to a front-end server. The cluster is running the Message Passing Interface (MPI) software in support of teaching and research in the area of parallel and distributed computing. A high-end SGI workstation can be used for front-end visualization.
Other Computing Facilities
Other equipment currently utilized by the department includes several SUN workstations, DEC AlphaStations, Pentium PCs, Macintosh and PowerPCs, and numerous terminals, scanners, laser and line printers.
In addition to on-site equipment, the department has limited access to a variety of other machines via its connection to the University's backbone network. This equipment includes the computational facilities of the LSU System Network Computer Center (SNCC). SNCC operates an IBM mainframe, an IBM SP2 supercomputer, and several RS/6000 UNIX (AIX) workstations and servers. Many computers on campus are also available for use, especially in the public labs funded by the student technology fee. Finally, the PAWS (Personal Access Web Services) system provides all LSU students and faculty with e-mail accounts, web services, and resources for instruction.

Pretty sweet if you ask me.
