Thanks Kevin.  Good to know my brain aint too far off.  I'll try the second drive 
approach...  (incidently, that's my last hard drive with an MS OS on it... :D)

I don't have to worry about KDE at all - this is a headless server.  I had it in my 
head at one point to set up remote desktop capabilities with it so I can access a 
common gui from remote locations.  But, SSH does most of what I need (file access in 
particular).

I did do an emerge -C for KDE and X, which removed most of it.  But I have some 
installed packages that are still compiled with X and KDE support and such.  Maybe I'm 
still too microsoftish, but I like a fresh, clean start every once in a while...  Oh, 
and in addition, they've changed the Portage tree at the start of August, so a rebuild 
here will accomodate that as well...

I'll let ya know if I have any problems or hiccups...

Shawn

Throw in your second HDD, start an ssh session to the local box, chroot, and 
build.  You can save a significant amount of time by just copying over the 
kernel from your current box, but really, in this case, I'd do the build 
through an SSH console, and then you'd have your primary box up and running 
for the duration anyway.

This allows you to build up the new box, with ZERO downtime (except the 
reboot).

2-3 days is pretty harsh.  I built from a stage 1 on a P4 1.7 with 512 RAM in 
about 24 hours.  Including all of X & KDE (which is by FAR the longest 
compile at maybe 18 or 20 of the 24 hours).  I wasn't just sitting waiting, 
so I'm not sure how much time I lost between the stages as one completed and 
I didn't check back.  Personally, I'd recommend skipping KDE until there's an 
ebuild for 3.3.  Just last on the old box for a few more days.  If you need, 
you can just compile the parts of KDE that you want, and then add in the rest 
later.  (emerge kdebase, and other important stuff first, and then once 
you're using the new box, worry about games and stuff)

I mentioned a variable yesterday or the day before for make.conf that should 
allow you to do this all without even really impacting your currently 
functional boxes performance.

Be careful with Grub, or you'll just keep going with your old box.  That's 
about the only major deviation from normal I can think of...

It's cool to rebuild a new PC while you're still using it.  Frankly, that's 
one of the things I like BEST about Gentoo.  No downtime.  Which is really 
ironic when you think about how long the compile takes...

Out of curiosity, did you try just unmerging the packages you didn't want?  
I've found it to be pretty successful.  It would be a shame to spend time 
rebuilding a box if unmerge was all you needed...

Kev.
