I'll echo this advice.

I guess I'm spoiled to my EMC arrays, which light a yellow LED on the DAE and 
on the individual drive, as well as telling you which backend bus, which 
enclosure, and which drive in that enclosure.  And the EMC-custom firmware is 
paranoid about errors.

But my personal box is a used SuperMicro dual Xeon I got at the depth of the 
recession in December 2009, and paid a song and half a dance for it.  It had 
the six bay hotswap SCSI, and I replaced it with the six bay hotswap SATA, put 
in a used (and cheap) 3Ware 9500S controller, and have a RAID5 of four 250GB 
drives for the boot and root volumes, and an MD RAID1 pair of 750GB drives for 
/home.  The Supermicro motherboard didn't have SATA ports, but I got a 64-bit 
PCI-X dual internal SATA/dual eSATA low-profile board with the low-profile 
bracket to fit the 2U case.  Total cost <$500.
