I submitted this story yesterday (with the link). Seems they prefered the submission without the link over mine. ;)- mods/

Here's a link to "The Miss Kanna PC", the anime case mod that made the #1 spot:

This page includes construction details and lots of pictures of the building process. Looks like quite an amazing amount of work went into this...
There are tons of wierd and wonderful casemods on this site

They have a steady stream of people sending in photos of their work.

Some more details: It's actually no regular PC, but a PowerPC system called Pegasos. The system has a PowerPC 750CXe @ 600MHz, Radeon RV100 gfxcard, HDD (just about visible inside) and a slot DVD-drive (accessable from the above, not visible in the pictures). The display is a LCD screen modded to the microwave door. It's running MorphOS operating system.
When we demoed the system at Assembly '03, some kids actually almost tried to heat their food with the thing. Lots of fun ensued.

Nano-ITX is looking to be a very small package (12cm x 12cm) so we are likely to see some even more abitious case mods over time. Most of my favourite case mods are where people mount Mini-ITX boards in classic games consoles like the NES.

the fabricator notices that he keeps dulling his drill bits. There are two reasons for that.
First, drill bit rpm is TOO HIGH. Stainless steel has poor thermal conductivity, and will not draw heat away from the drill bit very well. The drill bit cutting edge will go over temperature and soften and dull over.
This nice PDF chart should be printed out and put next to your drill press:
http://www.etec.wwu.edu/faculty/McKell/rpm%20ipm%2 0charts.pdf
It shows an allowable speed (surface feet per minute) of 30 for stainless steel. Note this is the same as for titanium.

using the formula RPM=SFM ÷ 0.262 ÷ DRILL DIA
and you end up with for a 1/4 inch hole 30 ÷ 0.262 ÷ .25 = 458 RPM
Thats about 7 revolutions per second.. pretty slow.
These reccomended RPMs/SFM are for factory production where time is money. I usually run at a lower RPM than (half as fast or less) because I am not in a hurry. The drill will last much longer the slower you go.
The second problem is the work hardening of stainless steel. If the drill bit is allowed to rub the surface without making a chip for even one revolution, the surface of the stainless will harden and dull the bit. You must press hard so that chips start forming immediately. If you must stop to raise the drill to clear chips for deep holes then raise the bit very quickly. Don't let the bit rub in the hole without cutting at any time.
Finally, the cutting lubricant: I use rubbing-alcohol+water mixture. It boils away in the drill hole to cool the bit, and does not leave an oily mess on the work.
