Anyone ever build a computer from scratch?

Has anyone ever done it? I'm building a micro linux computer that should be able to fit in an altoids box. It's going to be running an Atmel ARM chip at 400mhz. If anyone has done anything similar, suggestions are appreciated!

Well i don't know if anyone besides the original creators of the computer have ever built an ENTIRE computer from scratch, i mean, you would have to get a lot of silicon...and melt it....and stuff...that sounds really hard. I would recommended against trying to build your computer from /scratch/

Hi, i'm wondering if you're been able to do it.. I'm planning on making something of an open source tablet. But it's going to be an adventure to start with a blank ARM processor.. Ideas for me?

How do you actually plan to make such a small computer that has all the outputs...and inputs...and the power... :O

well, all the computer would be (like an ipod or a smart cell phone) is a suped up microcontroller (kinda, it has external components). The majority of the pins are for RAM and memory, and a lot of them have USB capabilities built right into the chip, very little external components are required, just a couple of ICs with decoupling capacitors.
Ah I see... And how is it going along? What about the ultra small Tesla coil that you were building??? Thanks !

i have a tendensy to start and not finish projects :P The farthest I really ever got into this project was read a whole lot of datasheets and did a lot of research, but nothing ever physical. On another note, right now I'm repainting my 728 Jornada and adding in some additional features via an AVR microcontroller. The Tesla Coil is going alright, still working on it every now and then, but school and friends has taken up the majority of my time. (~34 days of school left, yay)
Yea, I know what you mean... Well, good luck with all your projects... I have about 40 days of school left... :P

Sounds like a BeagleBoard
There were some less complete boards built onto SODIMM form factor boards.
Here's one example but search for "sodimm arm" will turn up more.

Building one from scratch probably means PCBs with more than 4 layers, BGA packages, and other feats of fine-pitch soldering well beyond amateur skills. IMO.

Answering to a bunch of the comments: I was thinking of building my own "motherboard" type circuit board with all parts built in, like ram and stuff. It'd run uClinux BTW by scratch I mean solder it all together, not get all the parts and plug them together. Also, everything but the circuit board should cost around 40-50 dollars including shipping, assuming all goes well
