Re: Finaly a cheap possible wearable solution?

I'm looking at the box right now... I can't find a model number, but mine is
the Via Epia with the 800 MHz C3 onboard.  It has a heat sink on the CPU,
but no fan.  I'm not currently wearing it, because I don't have a HMD.  The
mobo and drives are packaged in a shoe box with an old 150 watt ATX psu.

By the way, I'm poor, so I had to buy regular full-size desktop drives, and
the power supply unit isn't miniature or anything.  I'm amazed that I got a
5 1/4 CDROM, 3 1/2 HD, full size ATX psu, plus the motherboard into a
regular (not oversized) shoe box.  I used the I/O bevel that came with the
motherboard.  Just cut out a place for it and mounted it in the cardboard.
