I used the kind of standoffs you would use for a normal computer case.
I had to use a nut on the outside and a washer on the inside because
the metal was so thin and soft. Drilling holes was a challenge
because of the thinness/softness of the metal. Any burrs or flanges
are a big cutting hazard, hence the grommets. Maybe a drill press
would allow one to get very smooth holes.
In the end, I felt that this kind of tin box was too much of a bother.
I greatly preferred using the cardboard box and a utility knife.

I believe the boot time between a hard drive, a good quality flash
drive, and network booting is practically indistinguishable. It's
about 1 minute from pressing the power button until mythfrontend
displays the main menu.
I'm using Fedora 10 -- actually MythDora 10.21, with the kernel
updated to 188.8.131.52 because of an NFS performance bug in 2.6.27, and
with the myth applications compiled from trunk. I understand the
Ubuntu has tools for setting up netboot clients, but for Fedora I
needed to roll my own. I found it very helpful to start by installing
onto a temporary hard drive or flash drive, then clone that onto the
NFS server, and then work on the netbooting infrastructure. I
documented my own journey at

I happen to use a StreamZap IR receiver, which works well.
