This is an interesting way to cool a PC. There are 70 case fans in total, covering over 95% of the case AND THEY ALL WORK! Looking from the front of the case, air flows in through the left side and out the right side. The front an back blow air into the case and air flows from the top of the case down and out the bottom… theoretically anyway. [via] Link.

VoIP, POTS, SIP, h.323 and IAX are covered. If you’re considering a an open source PBX check out the Asterisk info and resources in the article Link.
DIYParts.org is a grassroots effort that enables and ecourages the sharing and trading of computer parts that are still useful, but would otherwise mostl likely end up discarded…one of the goals of the project is to get unused older personal computer systems to parts of the developing world and to people who have thus far been sidelined in the “digital revolution”. The old hardware can be made useful by loading it with open source operating systems like GNU/Linux. [via] Link.
The Sprint Treo 650 is… notable for what it does not include: dial-up networking (or DUN) over Bluetooth. Fortunately, a skilled Treo 650 user (known only as shadowmite) spent several hours tracing code and discovered that Sprint had not removed DUN; they had merely hidden it. A two-byte change in the Treo’s Bluetooth management code reveals the hidden setting. Trevor Harmon has posted step by step for setting up dial-up networking with the Sprint Treo 650 smartphone using Bluetooth and Mac OS X. [via] Link.
Mash-up artists and remixers have lacked a single, killer app, but they may have just gotten it. Ableton Live 5 now (finally) supports MP3s, instantly searching your entire hard drive for audio files. Drag and drop audio in, and the software instantly tempo-matches and slices up beats for manipulation. Once this hits public beta shortly, we may see the mash-up scene explode. Link.

A few months ago we posted up about the $11 Mattel JuiceBox project, some photos in the MAKE Flickr Photo Pool and some resources for hacking up these little guys for other projects. Slashdot has a story on it today with a lot more comments and resources that might come in handy too. Link.
