Ah, that makes slightly more sense then.

Well, I'm not *that* new. I knew that. I've read the handbook (and 
several other Gentoo docs) several times over. (I always RTFM!). I've 
got a Hush PC (EPIA M10000) up and running (mostly -- haven't finished 
the mpeg decoder stuff yet, no time), a dual PIII-733 and now my dual 
Athlon (w/the 2.6.1 gentoo-dev-sources kernel). The freakin' dpt_i2o 
driver for my Adaptec SCSI RAID card cost me quite a bit of time 
because I didn't google on it earlier (its broke as hell, has been for 
quite some time, but still in the kernel source tree with no warning 
for some stupid reason, and the fix is to use i2o_scsi instead of 
dpt_i2o)...

Anyhow, enough ranting. Well, maybe a bit more.... I certainly do like 
the optimization and speed of Gentoo, and setting it up is pretty fun 
(in a VERY geeky way, guilty as charged), but a royal PITA if you want 
lots of boxes, and/or need to reinstall (I'm still a Red Hat loyalist 
when it comes to critical systems ;-).

Yeah, if I didn't have to compile the compiler twice, I'd have cut an 
hour off my time, then the numbers start to make more sense, assuming 
his Opteron is a dual.

Uh, so why use all that power on a system that isn't even possible 
right now?!? Preparing for the future and 2nd-gen 4000x3000p HDTV? ;-p

I've looked at the Overture quite a bit lately, and its just too damned 
deep for my taste (and space). I like that it takes a full ATX, but I 
think I'd rather go with the new CoolerMaster that takes the same (and 
its all black, instead of that silver junk mixed in)... My secondary 
system is in a plain-jane InWin case that I'd like to replace with 
something less beige. Perhaps I get the new CoolerMaster, a new ATX 
nForce2 mobo and move the current primary upstairs... (thinkin' out 
loud :-).
