This was my favorite build from that site: https://www.mini-itx.com/projects/psu-pc/

Sounds like a fun project and very cool for the nostalgic people (like me).

A bit off topic, but I also loved the fact that the website remains like an antique website from that era (I know the article is from 2003 but the design is clearly not "modern"). I am going to say something probably stupid, but I feel there is a correlation between old/vintage design = good content.

Back when software came in boxes.

The final embellishment of making it automatically "dual boot" between XP and Red Hat Linux is a very nice touch.

benheck built a luggable computer into an MGD beer case around the early 00s as well. The build log and pictures seem to be lost to time but I recall it having a flip-open disc door that was cut out of the side of it. I didn't appreciate the humor as a kid but having had a beer or two in my day it's a lot funnier in retrospect.

I used to love the mini-itx form factor. For the time, lots of features in a compact space. I think micro atx might be a more popular form factor now?

Just last night I won an auction for a dual Pentium III supermicro setup with 1GB of memory. To relive this era of computing, including simulating my high school network by deploying Netware in a lab.

Reminds me of running good old TinyXP.
