It is difficult to give you general advice on this broad a topic in an
e-mail reply. I'll limit myself to a few specifics you might find helpful.
First, Linux runs properly on pretty much any CPU/mobo conbination that
works from a hardware standpoint. There are occasional reports of problems
with specific bus chipsets in some applications, though, so your safest
approach is to check the chipset on any mobo you are considering and Google
it for Linux information.
Aside perhaps from Firewire (which I'm just not familiar with), Linux has
support for all the requirements you mention in your list.
With the display you want, I assume you primarily want to work in X. This
should present no problem with any modern graphics card -- though your best
bet for checking card/chipset details is the compatibility list at
www.xfree86.org -- except for playback of full-motion video. Here you have
two special considerations.
One, for efficient playback of video, you want an X server that supports
the xVideo (XV) extensions that give video apps direct access to the video
hardware. Many recent X servers do this, but people on video lists seem to
favor nVidia cards in particular, using a proprietary X driver that nVidia
makes available on a non-Open Source basis. (Whether this is an option for
you depends on the strength of your commitment to Open Source software.)
Two, you may want a video card that supports output to a TV. This limits
your choice quite a bit, because it is difficult to find an X server that
supports both xVideo and TV out. (The NVidia driver I mentioned above does
support both, BTW, which is an important part of why it is popular in
video-on-Linux circles.) See my comments on vidcap below for a bit more on
this.
While Linux supports pretty much any modern chipset for audio output, it is
occasionally picky as to audio input. I've had trouble with the OSS drivers
for the VIA chipset, as an example (but the newer ALSA drivers worked OK).
Video capture can be done in many ways. My own experience is with
BTTV-based vidcap cards like the Hauppauge Win-TV Go and a similar
Avermedia card. They can capture a realtime video signal from
broadcast/cable source, from Composite in, and sometimes from S-Video in,
but they rely on software to encode the video to (say) MPEG4/DivX. Newer,
more expensive vidcap cards, like the Hauppauge PVR-250, have onboard
hardware encoders that do realtime encoding to MPEG2. Software encodding
demands a lot of CPU time ... when capturing, you need to be careful about
what else the system is doing to avoid dropped frames, especially with what
I think of as a "median-level CPU" (a 2 GHz Celeron or thereabouts) ... but
hardware encoding uses very little CPU time. And a newer Hauppauge card,
the PVR-350, has TV out with hardware decoding as well.
Though you mention "ssh'ing into work", you don't mention what sort of
Internet access you expect the system to have. Linux supports dial-up just
fine, and broadband access via cable and DSL is well supported with
Ethernet-based broadband "modems" ... I'm not sure how good support for
USB-based broadband "modems" is (it used to benon-existent).
I haven't used a DVD burner yet with Linux, but I think you want to check
the software options before you buy one. In particular, check whether the
app you prefer supports both the + and - standard (at least one does, but
I've seen at least one other that only supported +). I've never run into a
CD burner that did not work with Linux, so I expect all modern internal
(ATAPI or SCSI) ones at least will work fine.
Finally, I usually buy my hardware locally and built my new Linux machines
from parts (though I do convert old Windows machines, for example a 533 MHz
Celeron E-Machine, for special purpose uses). But this works because I live
in Palo Alto, California, in walking distance of a good electronics
discounter, Fry's Electronics. You can get good deals online, but what your
best choice is depends too much on where you live for general advice to
apply. On that score, you need some help from someone in New Jersey, or at
least somewhere in the Greater New York metro area.
There used to be a Linux Compatibility HowTo, which you can look for in the
usual places. If it's been kept up to date, it will be a good place to
explore your hardware questions.
I don't know if this sort of general response is helpful or not. You might
do better to look at the HowTo, find out what variety of hardware is
readily available to you, and come back here with specific questions.
