I just bought a Zotac board with plans to do something like what you
have done.  A couple of questions:

1. In the case when you used the metal tinbox, what kind of standoffs
did you use to mount the motherboard?  (I'm worried about shorting
something out.)  Also, did you consider drilling a bunch of small
holes in the box rather then a few large ones?  I''m thinking that
would eliminate the need for the rubber grommets and smaller holes
would make it even less likely that something would fall in the top.

2. It sounds like you eventually abandoned the use of the USB flash
drive for network booting.
Any issues with getting network booting working?  What base OS
distribution are you
booting (and what OS is hosting the boot environment)?  Any pointers
to docs would be appreciated.  What is the boot time like for network
vs. USB flash?  I'm wondering
about WAF here...

3. For the moment, I've decided to put one of my HDHR's in the living
room so I can use it's
IR receiver with lirc to control the Zotac frontend.  If I change my
mind, what USB IR did you use?

4. Finally (to the world): Has anybody figured out a way to somehow
add a firewire port to the Zotac board so I can talk to my cable STB?
I don't need wireless access so I could try to use the mini-pci
slot.The only other option, I can think of is some kind of USB to
Firewire adapter.  I started looking into that, but haven't found
anything that looks promising for under $50.
