512Mb should be adequate - it really depends on what you're going to be doing with the system.... I run SUSE 8.2 Pro on my laptop with only 256Mb RAM, and it does me well for day-to-day stuff (programming, remote admin, web development) - the RAM is always almost completely in use, and swap activity is very minimal. If you're going to be doing anything really intensive (video editing and the like), and you've got the $/£ to do it, then a gig of RAM is never going to be a bad thing.
We've had big problems with IDE RAID at work (this is on a Windows 2003 Terminal Server however) - some of the new HP Proliants come with a two disk mirror - and the RAID tools provided by HP are useless, you end up having to bring the entire server down, going into the RAID setup and rebuild whilst the servers offline - defeats the purpose totally - it'd be just as easy to fit a new disk and restore from a backup - it'd be twice as fast too.... I've played around with software RAID under SUSE before, and I've got a little article on my site
here although this will most probably be irrelevant for your purposes as the RAID board should take care of RAID management and control anyway.....

AAC(4) BSD Kernel Interfaces Manual AAC(4)
NAME
aac -- Adaptec AdvancedRAID Controller driver
SYNOPSIS
aac* at pci? dev ? function ?
ld* at aac? unit ?
DESCRIPTION
The aac driver provides support for the Adaptec AAC family of SCSI and SATA RAID controllers. These controllers support RAID 0, 1, 5, 10,
and volume sets. They have four channels in the add-in version or 1-2 channels in the motherboard integrated version, and are most often
found rebadged by Dell, Hewlett-Packard or IBM. Supported controllers include:
o Adaptec AAC-364
o Adaptec SCSI RAID 2120S
o Adaptec SCSI RAID 2200S
o Adaptec SATA RAID 2410SA
o Adaptec SATA RAID 3405
o Adaptec SCSI RAID 5400S
o Dell PERC 2/Si
o Dell PERC 2/QC
o Dell PERC 3/Di
o Dell PERC 3/Si
o Dell PERC 320/DC
o Dell CERC SATA RAID 1.5/6ch
o HP NetRAID 4M
o HP ML110 G2 (Adaptec SATA RAID 2610SA)
o IBM ServeRAID 8k
Access to RAID containers is available via the ld device driver. Individual drives cannot be accessed unless they are part of a container or
volume set, and non-fixed disks cannot be accessed. Containers can be configured by using the on-board BIOS utility of the card.
DIAGNOSTICS
The adapter can send status and alert messages asynchronously to the driver. These messages are printed on the system console.
SEE ALSO
intro(4), ld(4)
HISTORY
The aac driver first appeared in NetBSD 1.6, and was based on the FreeBSD driver of the same name.
BUGS
This driver is not compatible with controllers that have version 1.x firmware. The firmware version is the same as the kernel version
printed in the BIOS POST and driver attach messages.
