Typical...
Now that I've built my new machine, the motherboard that I originally intended to buy (Asus A8N-SLI Premium) is now available at a number of online merchants, including ZipZoomFly. Even more irksome is the fact that Asus has rectified the dodgey chipset fan issue by replacing it with a fanless heatpipe. I can't get a refund for my current motherboard, of course. So, I'll just have to be happy with what I have (which I am, truly).
I've also decided to replace the chipset fan with a Zalman NB47J passive heatsink, though. From what I've read, cooling shouldn't be a problem, especially with the volume of air moving through my case.
Life goes on...
