It's unlikely that you'd be able to swap the drive into a different PC and
boot successfully. It usually requires a repair installation. (You can do
this if you have retail upgrade or full version of XP. If you have an OEM
copy, it may not be transferable.)
Some would recommend a complete format/ new installation, but that's a lot
of work, and I don't think it should be necessary. (Compulsive behavior has
its uses, but it's very time-consuming.)
First, back up the drive in the old system (or at least the C: partition, if
you have more than one). Swap the HD into the new system.
Do a repair installation:

"How to Perform an In-Place Upgrade (Reinstallation) of Windows XP"
(In brief: change the BIOS settings on the PC to boot from the CD drive.
Boot from the XP CD. Choose to install rather than going to the repair
console. Under install, choose repair rather than new.)
Some warnings:
You'll have to activate XP again on the new hardware. If it has been more
than 120 days since the last activation, you can activate via the Net, like
a new installation. If it has been fewer days than this, you may have to use
the telephone option (toll free call in the US). Explain to the MS rep that
you're upgrading, and that XP will be running on one system. It's an
annoyance, but it only lasts about five minutes.
You will lose everything installed via Windows Update. (Most applications
and settings should be preserved.)
(There is supposed to be a technique that permits deleting the drivers in
the old system and having then re-detected in the new, but I've not tried
it.)
Another warning: as you have a PIII 800, you may be disappointed in the
performance of a P4 1.2 GHz , especially if it uses PC133 SDRAM memory.
(RAMBUS or DDR are preferred.)
On the other hand, I believe that the slowest P4 that Intel has sold was a
1.3 GHz, so you must have something other than 1.2.
HTH.
