Lunchbox Computers for Live Music Performances?
Dan Reetz asks: "As a PC based musician, mobility is critical. However, most laptops have horrible soundcards. PCMCIA cards like a VXPocket cost about 700 clams. A friend of mine recommended I look into 'lunchbox' style computers as a portable solution. A few searches revealed them to be quite expensive and they are hard to find used. Does anyone know of a source for used Lunchbox PC's (even just the diplay would be fine) or a better low latency/noise audio solution for laptops?"
I've seen Shuttle SV24s with pretty good kits inside of them. Starting at $250 buy-in, that's not bad. Also, I've seen one where a guy bolted on an Amp Strap to the top of the case, which seemed to work well.
What about the empeg? http://www.empeg.com
M-Audio and one other manufacturor (I can't remember their name) make USB and Firewire break out boxes for laptops with Audio In/Out (Balanced XLRS, 1/4 stereo and mono) with on-board high-quality DACs.
I'm looking to get the M-Audio one for my iBook to do digital recording as Macs don't come with Audio in anymore, leaving it up to third parties to make Firewire/USB solutions. They have low latency (I would image the Firewire one would be lower due to Firewire's higher transfer rate), but I've heard nothing but good things about them.
Also, if you're doing sequencing, you can get a MIDI breakout box and connect to another MIDI device for audio output.
Why not get a USB audio device? I have the Audiosport Quattro and it works great. www.edirol.com has some nice cheaper ones as well.
Seriously, its not really that hard. Check out the case and cooling forum at ArsTechnica:= fr m&s=50009562&f=77909585

Search around and I'm sure you'll find guidelines on how to build if not a lunchbox computer, at least a suitcase computer.
Why replace a whole computer (with a $999+ component from ThinkGeek, perhapse)? Keep the laptop, but use a different method of getting the tunes *OUT*.
You know that PCMCIA cards suck. Have you tried USB or maybe Paraell port? I know of one product, lp3, hooks into the paraell port and you basically print the MP3 to it. Unfortunately the lp3 is not shipping (they're having problems handling shipping).
I've also heard of the LPBlaster, and of course numerous supported USB audio devices...

The Apple PowerBooks have a good reputation among musicians. Apple has posted a page of music-related technologies for the PowerMac line, such as the AudioSport Quattro 24/96, described as "24-bit 96kHz USB audio and MIDI interface with direct monitoring switches; 4x4 audio interface; with ASIO and OMS MIDI drivers."
There was a similar article on Slashdot (a long time ago, not a dig at /. editors) which should have some good ideas for you. I only remember it because I was the one who asked the question.
Kind thoughts do not change the world
Check out CyberResearch (PDF) or Their Website for some nice machines like you describe. I know I've posted about them before, I used to work for them, and while, this stuff is not cheap, it is high quality and they stand behind it. If this is going to be your livelyhood, why not do it right the first time. I'd rather spend $3000 once then spend $1000 4 times.
Don't Tread on Me
This case and appropriate components (flatpanel monitor) could work well for this, so long as you have a nice PCI, USB, or firewire device for your audio. Of course, I don't know if having everything so cramped increases interference in the audio components, but if you are really in need of this quality you probably want a set up that keeps things digital until the signal is well away from the computer itself.
XML is like violence. If it doesn't solve the problem, use more.
Here's a site devoted to getting mobile music out of your notebook.
He recommends the "EMU8710" and the "WaMi Box". A quick net search shows 'em both running about $400 - a little more reasonable than the $700 quoted above.
If it ain't broke, it doesn't have enough features yet.
EgoSys has two products that you could use for notebooks: WaMi Box, which is a PCMCIA, and Waveterminal U2A, which is supposedly very good.

Any technology distinguishable from magic, is insufficiently advanced.
Midiman makes the quattro usb based sound system that apparently has very low latency and excelent quality. The price is pretty low too. It has 4 i/o's and you can get the omni system that adds 8 more inputs to it

I'm also an electronic musician and have had good luck with USB audio adapters.
There are three rather good cheap ones out right now:
- The iMic which works on Win32 machines and run for $35, check out their stats at www.griffintechnology.com. 24 bit/48khz, etc.
As well as the somewhat cheap entries from Emagic and Roland/Edirol
All three support ASIO, I believe. I've never experienced any performance issues with USB audio devices, as the USB bandwidth is more than enough to handle audio tasks.
Screw the lunchbox, and just stick with the laptop, it's much easier to work from one computer, and if you're like me, you're surgically attached to your laptop.
I've had great results with my MOTU 828. It's a rack-mount unit that connects to my laptop via Firewire, with many digital (2 channel S/PDIF I/O, 8 channel 24-bit ADAT lightpipe) and analog inputs (6 1/4" and 2 Neutrik XLR/TRS combo connectors with optional 48v phantom power), all with 24-bit converters w/excellent range) and outputs (8 1/4"). It's rack mountable, it's got drivers for PC and Mac, and it's very dependable -- I've had absolutely no problems whatsoever. And it ships with both ASIO and WDM drivers for PC, which means that it will work with any sequencer or audio program.
Building Better Software
Here's a nice breakdown of the laptop audio interface options (geared towards PowerBooks, but all of these are available for PC, too).

I have the Emagic EMI 2|6 myself, which I like a lot. I'd look at a number of these solutions rather than a "lunchbox" computer.

I used to do a lot of tracker and MIDI music and I learned many helpful tips about eliminating audio noise in electronic systems:
- "It's just a matter of opinion!" - PRIMUS
24bitfaq.org is an excellent resource for high quality moble recording info.

I use a notebook computer for live performances, and bought the Emagic EMI 2|6 USB audio interface. It's great. 24-bit DAC, 48 KHz, 2 ins, 6 outs, coaxial S/PDIF, $325. If you use Logic Audio like me, then it gives you the added bonus of low-latency virtual instrument playback. Check it out.
I think this was posted on /. once. These will probably help you:

This case is just barely bigger than an ATX motherboard (and won't fit the larger ones). Put a good sound and video card in here and the resulting machine should be quite small and light. Though you'll still need a TV or monitor of some kind.

That would be the sv24 made by shuttle, available at Newegg.com.
only 1 expansion slot though...
USB audio is the way to go.
