Those are Canadian prices and I'll be shopping around for cheaper. So, as you might have noticed from the pricier cooler and case, I'm going for quiet but powerful, with slight overclock potential without running into heat issues and I don't want full ATX. I'm curious to know what people would do differently. The PSU is only 850W but I don't plan on upgrading the GPU to something more power hungry or adding two of them, so it should be fine. If you think that PSU is crap and you'd get a different one that's more reliable, I'm interested in hearing what you'd get.
And just to be clear - I'm not switching to Linux. This is just a cheap additional machine to help on some new animation projects until the new Mac Pros come out next year. I will actually be trying this machine out as a Hackintosh as part of the article and that's part of the reason I chose the parts that I did: http://www.tonymacx86.com/viewtopic.php?t=59573
