However if I wanted to go all out SERIOUS.....
I would start with this, http://www.frozencpu.com/cas-208.html#
sure we can, but we want a audio component to at least make an attempt at looking like one, which the Musica does and would sit nicely in a audio component rack. Although the lines are blurring, i would not consider this an entry into the HTPC arena; more like a digital source component like a CD player
and if you think people don't care about looks - then check out the iPod sales.
Well I suppose you could dress it up.... You say looks though; I have seen an awful lot of rack mount looking audio equipment too....
Perhaps you missed the point; the Zalman is FANLESS in all ways. It will never make a peep, but you can stuff it with hardware capable of doing any thing, unlike any thing else with no fans is capable of doing. Plus you can make it a hidden device, there is no reason why you could not put it on the other side of a wall behind your staging area, or behind an entertainment center or some thing. Even just setting it by the side of other stuff would be tolerable as opposed to opening it etc, while having remote control and drive access. Papajin the top one is close to the Zalman, but still has fans for options, the Zalman will never need one. The Zalman even has cooling for the hard drive, as well as a no compromise PSU that is fan-less but not a heat box.
The capability of building your own is precious or even building one starting with the Zalman and distributing... Fiber SPDIF, coaxil SPDIF, DVI and Analog, HD component, S-video, composite video, RCA, XLR, the inputs and outputs alone are worth a think.
As I said before, a zero compromise situation no holds bar, nothing but the best stuff. There is no one capable of making all of their own components to compete; the closest thing will be the PS3.
Looks are a plus; to be picky enough to turn things down no matter how good they are is silly. You listen to music or watch movies with this equipment, not stare at the component. This is beginning to sound like using a computer, well it is but you can make your own program and setup so it will all be automated, and leave you with nothing to worry about.
Feisal K, Ipod sales.... I am sure there is a graph based on audiophiles purchasing Ipods based on the level of cuteness, some where.
