Unfortunately dmesg is one of the best places to get this sort of stuff,
because it's about the *only* place where information about multiple
types of hardware ends up. If your machine has been up for a long time
the boot messages have likely cycled off, but Redhat and Mandrake in
particular (and likely others that I don't have personal experience of)
save the output at boot time to /var/log/dmesg. Let's look at mine (I
won't fill the email with the whole thing):

It's not quite a round number, but I have a 500MHz CPU.

I have 192MB of RAM.

My CPU is an Intel Celeron.

This is telling me I have three serial ports (they equate to COM1, COM2,
and COM4 in DOS). Unfortunately what it doesn't say is that the first
two are actual serial ports, the third is a modem.

I have two hard drives, one a 2.5gb, and one a 13gb, and a 40X CD-ROM
drive. hda and hdb are on the primary IDE channel, hdc and hdd are the
second, so, the two hard drives are sharing a channel and the CD-ROM has
one to itself.
You can also use the lspci command which should be on most distros
(Mandrake and Redhat have it, anyway):

These tell me my motherboard is based on the Intel BX chipset.

These don't say much of note other than confirming it's an Intel based
motherboard.

My network card is using a DEC chip, it's Tulip based but this doesn't
actually say so.

My video card is a TNT2.
There are various utilities around that collate some of this stuff,
there's one somewhere in GNOME I believe, but I wouldn't remember how to
find it.
