Sorry not trolling....this is a pc isn't it ?....although the price appears be to competitive, forgive my lack of googling but what is the benefit of buying this pc rather than going down to asda and buying an "off the shelf" special ?
I think the two key benefits are that all profits go back into AROS development, and all the hardware supplied is tested and therefore guaranteed to work with AROS out of the box... no fiddling
If you don't mind fiddling around a bit, then you could just build or buy your own PC.
