cluster question

Hi,
Iàd like to do some testing on a linux cluster. This will be a 2 PC
cluster with am apache 2 web server, php 4 and mysql 4. At this stage I
can't buy two dedicated servers so I have to use 2 workstation-class PC
(with SCSI disks). The PCs are identical except for the SCSI DAT
installed on one machine. Is it possible to do something without shared
storage ? I hought that maybe I can setup a virtual RAID (mirroring)
between two disks, one of the first PC and one of the second. Is it
possible ? Any other alternative for keeping the data between the two
PCs synchronized ? I can use the mysql replication feature for the DB
but whatàs about the web server (I need to upload data from the web
browser) ?

TIA

Maybe rsync ( http://samba.anu.edu.au/rsync/ ) to keep the web servers
in sync and heartbeat ( http://linux-ha.org/ ) for failover ?
