It looks like the 800rpm slipstream fan can only be bought from the US. I've found them for $7.99 at jab-tech and shipping costs $34. This means I can get three 800rpm slipstreams for the case and one 1200rpm for the heatsink for about £33. Is this worth it considering noctua's are about £13 each...

Re: acrylic cases
I suppose that a big potential problem would be heat, since steel and aluminum cases act as giant heatsinks... generally, a negligible amount of heat is lost through the case walls. i would say upwards of 90% of the heat is carried away by the forced air cooling. so i wouldn't expect an acrylic cas...

I guess one thing is that it would probably run cooler even though the wattage is negligible.
