Nice to see the price drop down - hopefully it will encourage more sales of the Iyonix. It's a good move and I've seen the Panther case and it actually looks good (my Iyonix is one of the older mini-towers). I suspect Castle are positioning the lower-end Iyonix against possible A9 competition. Given the IOP321's higher spec the only thing that might have counted against the Iyonix was price - and that now seems to have taken a move in the right direction.
Looks like 2005 should be interesting from a RISC OS hardware perspective
