Thought i buy one to test out MorphOS. Is it ok to use MorphOS on this one?
Yes it's OK. Spec's and expandability are limited, and you can't add more memory than the pre-fitted 128MB, but you can surely have much fun with it as it is! The low cost is probably its most prominent feature! :-)
Vesalia in Europe and Directron in USA has been mentioned, but I would also like to highlight
AusPPC in Australia, who does very nice "custom" casings for the Efika (he also ships internationally).
