Let's say, conservatively, that doing the research to know how to build this, having never built a pc before, takes 20 hours. I bill at 100-160 an hour, so let's take the low end and cut it in half, and say my opportunity cost is $50/hour. The cost of building one of these is (20 * 50) + 700 = 1700. If someone can build one for me at $1000 I'm money ahead. It's easy to forget that knowledge acquisition isnt free when you already poses the knowledge.

Couldn't you Google for a PC which has a graphics card with 300 or more cuda cores?

  If you're not following hardware, that google result isn't going to help much (other than maybe giving you an idea of basic cost of such a system). There's lots of ready-made vendors, generally they're all crap (for a certain value of crap). There's a big difference between building a one-off rig, and buying one, working with it for a year or so -- getting your code right -- and the knowing you can get 20 more (updated and/or cheaper) -- that won't have driver issues, heating issues or flaky psus. Sure, a contract can help, but whatever you get "back" in cases of failures are always going to be much less than whatever value you wanted in the first place (eg: the hardware ended up being free, but you weren't able to sequence the genome because of glitches). In short, don't underestimate the cost to acquire the required domain knowledge to do such a task well. One can always hope that the new Mac Pro will be successful enough that there'll be a decent Cuda story there -- but I'm not holding my breath. And after seeing what Apple did vs Final Cut pro and OS X server (esp: hardware) -- I'd be wary of trusting them with any production platform.

    I've read from http://www.reddit.com/r/buildapc http://www.reddit.com/r/buildapc that low-cost computers are cheaper from ready-made vendors. Not sure if you can buy a cheap ready-made PC with 300 cuda cores, though.
