Cheap And Flimsy PC Case Provides No Protection

computer-case-provides-no-protection

[Rafael] tipped us off about a “case mod” he completed for his PC. The email he sent provides no details and the link just shows five pictures of his computer in a “dead file” container (we’re guessing he doesn’t want to be an Internet sensation). What we get out of this is that he took a corrugated plastic box meant to house old files on shelves, and thew a set of computer parts inside of it.

This would be a great hack if [MacGyver] needed a computer to defuse a ticking bomb while trapped inside of a room built completely out of metal. The plastic provides protection from shorting out the motherboard but, other than low cost, that’s the only upside of this hack.

The downside here is obvious, there’s no protection from physical damage. In fact, a good bump might flex the box enough to slam the motherboard into the PSU housing. And what’s with the external WiFi fob? We could understand the point of this a bit better if it could blend in with a rack of archived files in the back room.

We give this one an ‘A’ for creativity, a ‘B-‘ for execution, and an ‘F’ for longevity. This should have been built in an acrylic case sized to fit perfectly in the yellow plastic box. But what does your unorthodox PC case look like? Let us know by sending in a tip.

Exploding Processors For Real

[youtube=http://www.youtube.com/watch?v=X3whIm282X0]

After we posted the “High explosives pc case” earlier we saw a resounding outcry in the comments for combustible destruction. Oddly enough, we got a submission of something along just those lines. [tazzik] has taken the heat sink off of his athlon 1400+ and covered the poor processor in potassium chlorate. As you can see in the video, this was not a very effective heat management decision. It is definitely fun, but nowhere near as explosive as our thermite shenanigans.

High Explosives PC Case

ammo_casemod

[Ilias] let us know about his new HTPC case mod.  He took a surplus Ammo-case and with a bit of work turned it into a livingroom eye-sore masterpiece. His build has some nice touches, including a slot-fed DVD player, switch-based fan control, and key-and-button “nuclear launch” type power-on controls.

A few things to learn from this project: Cleanly cutting holes in a steel case for the connectors is tough.  You can see that [Ilias] did a pretty good job with it and in several cases used rubber gaskets to cover the rough edges. Secondly, the slot fed DVD had to be mounted upside-down.  We assume this will be fine, but we’d like to hear a follow-up after a few years of heavy use. Finally, the GFAF (girlfriend acceptance factor) ran very close to critical on this build as [Ilias] didn’t clean up the metal shavings on his porch and ended up with rust stains everywhere.

Case mods are an enjoyable hobby. We hope this will inspire you to take the leap.  If you do, don’t forget to send your completed project into our tip line.

Building An IR Receiver For The Popcorn Hour C-200

IR_module

[Linuxworks] has posted a writeup on how to build an IR module for the popcorn hour c-200. We weren’t familiar with the popcorn hour c-200, so we had to look it up. It seems to be a media center pc sort of thing. We’re not reviewing the unit itself, since we’ve never used one, so we’ll just get back to the mod. The device uses an RF remote, which some people didn’t like as much. Luckily it has an expansion port which can be utilized to get IR signals into the machine. [Linuxworks] has used a cheap IR sensor and a standard headphone plug. He notes that equipment passing power through these plugs should be turned off before plugging them in or removing them as they short momentarily during insertion.

Microsoft Unveils Open Source Multi Core OS

group (Custom)

A new operating system, code named Barrelfish is being developed by Microsoft research labs and ETH Zurich in Switzerland. This operating system is being built with multi core operations foremost in priority. It is supposed to be extremely scalable and able to function on a very wide range of hardware. You can download the current snapshot of it on their site and dig into the source code, released under a 3-clause BSD style license. If you would like to learn the primary differences between this OS and Windows or Linux, you can read this PDF.

Internal Wireless Headphones

Wireless headphones can be a wonderful way to help clear up the clutter inherent in most desktop PC systems. However, after plugging a wall wart in, and the headphone jack into the computer, the number of wires used has actually doubled. After [Parker] found an old set of JVC 900 Mhz wireless headphones (and a generic 900MHz transmitter), he cracked open the case to see what he could do with them. Realizing that the transmitter used a 12V DC source, he powered it with an unused floppy connector (which provides +12V, +5V, and two ground lines). He also wired the audio-in line directly onto his sound card headers rather than feeding out a headphone jack to the back. He then wrapped the whole thing in plastic to prevent unwanted shorting and placed it back in his PC, leaving him with a very functional wireless system. Detailed photos after the break.

SLI Anytime Anywhere

slin_b

SLI, for those who don’t know, is the process of taking two Nvidia graphics cards and allowing them to work in parallel to render to a single monitor. In theory this doubles the power, getting more FPS for video games. Great right? Except due to encryption, only a limited amount of motherboards can actually support SLI.

That is, until now. Russian hackers at xDevs discovered that the newer encryption is based around string identifiers. This can be modified within the operating system itself, so in theory any motherboard could work. Be wary, this could brick your system; but if successful, you’ll have more power without shelling out for an officially SLI supported motherboard.
