Thanks for the positive responses, as mentioned iMica is for those not used to building a system. If you are happy to do so then you can get greater performance. Just remember drivers are still a problem and Vesa is still best mode at moment for graphics as it is very fast and very reliable. As for sound just get Soundblaster live with EMU10k chip off ebay for around $10.
More users the better I say.
I will soon be announcing Amiga 25th anniversary site which I hope to involve all people with all flavours of Amiga OS. The next couple of years should be good for all of us if we band together under Amiga banner with many flavours.
