Pico-ITX, Because Size Matters

An anonymous reader writes "It's not every day that a new form factor comes out, especially not one that is 10cm x 7.2cm. Despite its size, Pico-ITX is the hottest new thing in the rapidly changing small form factor market. It is considerably smaller than Mini-ITX (17cm x 17cm) which has proven itself to be quite versatile and though some sacrifices had to be made to shrink the platform, Pico-ITX is surprisingly complete. The system was tested with Feather Linux but the PX10000 has the power to run Windows XP or Ubuntu if you want to add on a hard drive."

Pretty small, but...

[Bombula]

I'm no expert and I know this thing is tiny, but aren't laptop motherboards already pretty small? The motherboards in some of those tiny Sony Vaios must not be much bigger than this thing, and thinner too - and they've been around for a few years now.

drop the legacy ports; minimal IO configuration

| two PS/2 connections and more.

we do not want a 'full range' of connectors -- because anything that wastes circuitry
for PS2 connections on a pico size board is a dodo (imo).

we DO NOT WANT: IDE, PS/2 or VGA connectors cluttering up our motherboard.
they duplicate functions already better achieved with: SATA, USB, and DVI.
we want as few ports as possible and still be able to achieve any function.
so, what ARE the desireable ports?

-USB 2.0 (four ports)
- SATA (two ports)
- DVI (with optional VGA header)
- SODIMM Slot for RAM (two)
- ethernet (10/100/1000)
- optional 802.11g/n

that's it -- no extra ones besides that.
get the bios working so it can boot with those,
and drop the legacy cruft.

No serial ports?

They say a lot of things but that's the stupidest thing I've heard all week. Connectivity of the "most common denominator" is lost with your collective desires, "We." IDE, PS/2 and VGA connectors are not legacy ports. They are standards that should be maintained because SATA, USB, and DVI do not duplicate and/or replace the functionality of the ports you wish to remove.

Yesterday I used a null modem and minicom to connect two systems via ttyS0. One of the boxes faces the internet and I don't want it to have IP-based login capabilities so that there is no risk of toll fraud. On many of my other servers I use PS/2 and VGA connectors with IP KVM's all the time for cheap OOB management.

I would not purchase a mobo w/o those connectors. They're a standard and NOT cruft. I'm looking at this from a server perspective though.
