Thanks for all your help - sounds as though I should be ok.

I was intending to go for a lower range graphics card - probably a GeForce 6200 PCI Express for now. That card seems to be fully supported according to the hardware list on the Suse site.

The hard-drive is one I already have - a 160GB Hitachi (Hitachi Deskstar 7K250 160GB S150). I've looked up the chipset of the SATA controller on the Asus website and it appears to be a Silicon Image 3114 RAID Controller if that means anything to anyone?

Thanks again for your help - it is much appreciated.
