For anyone who enjoys cutting holes in their computers, I have some good news: Dremel has released a new rotary tool called the "4000". This is the mac-daddy of all dremel tools. The motor was redesigned for smoother cutting, more consistant RPMs, more power, and better reliability. It is infinately adjustable between 5,000RPM and 35,000RPM. These things combined mean that it can do fine work better, while chewing through heavy work with ease. On top of all this it comes with a removable, adjustable perpindicular handle that makes fine control extremely easy. I just got mine today, and this thing is far superior to my old XPR400...and the XPR400 was the best rotary tool available. Cutting a line is easier than trying to follow the same line with a pencil. There is also a front-facing blower that makes it a whole lot easier to follow a pencil line (without it, metal dust tends to pile up and hide the line). The only potential drawback is the size...slightly larger than the XPR400 with the perpendicular grip removed. Some of the tricky cuts inside a case might not be reachable by this unit (or by the XPR400 for that matter). This isn't a big issue for me, because I also have a Dremel Stylus...a tiny, Li-On powered mini-dremel that also has a perpendicular grip, and has very good performance...at least for something so small that is battery powered. I've got to get back to modding my case now.
Interesting article. I think this would probably be better off in 'Other PC Hardware' but I haven't checked if you've put it there already.
