                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
         DEC AlphaServer 4100 with 1GB memory and 20GB HDD.

        ^^^^^^^^^^
        Most of micronics boards for Pentium II or Pentium Pro supports
        1GB RAM nowadays.
        Tyan's tahoe boards for Pentium II also supports max 1GB RAM.
        (http://www.tyan.com)

        Some of them have adaptec's on-board SCSI controller, supports
        dual-CPU, etc.
        
        P/I-P65NP5 board from Asus(Editor's choice, BYTE) supports
        max 512MB RAM, not sufficient for this cache.
        (http://www.asus.com)
        

> Ultra Wide SCSI 9G Disk X 3 (2 for cache, 1 for system and log)
                           ^^^^
        Seagate's Cheetah products(Editor's choice, BYTE) are running
        the state of the art in the area of disk performance though
        it's somewhat expensive(* 2).
        SCSI HDDs from IBM provide good performance compared to their cost.
        
> Ultra Wide SCSI IF X 2
        ^^^^^^^^^^^^^^^^^^^^^^^
        Adaptec's AHA 2940UW/3940UW.
        I'm not sure whether FREEBSD supports those devices or not.

          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
          1.8-2.5 million requests and 28-41GB in a day....
          SingNet cache would be a good reference cuz they've been dealing with
          2-3 million requests with 2 DEC AlphaServers.
