Sorry, but no totally awesome system in the works for me for at least a few more years. I want some new technologies like HDMI, USB 3.0, Nehalem, etc. to be settled first. I also want to use a projector as my monitor. Because that's just badass.
I would, however, like to hear about how you've pulled your custom stuff together, like the oil-cooled fishtank desktop, and what tangible advantages that affords (what, for example, is your overclocking rate?).
