There was a problem but this was fixed at 5.4. There are odd reports of
problems with older hardware. I have had a problem with an oldish quad
Compaq machine which I have not had time to get to the bottom of.

Have a look at the hardware compat list at
this may help with the raid card.

One thought I would separate the file server support from a development
machine. You may get into speed problems when heavily loaded. For my
network I use 2 modest machines with large IDE drives running a HA setup
as a file server. They sync to each other via a Gigbyte direct Ethernet
connection and if one goes down or if off line for maintenance the other
takes over. See http://linux-ha.org/ .
