There is a product from Red River Technology that you should know about.
It is an AT compatible system board with an XT compatible size/mounting
dimensions.  By purchasing this board you can replace the system board
in your xt, but keep chassis, power supply, disks, etc. (I don't know if
you can retain your keyboard.)  This board contains the new AT compatible
chipset from Chips and Technologies Inc. so it contains many fewer chips
than a traditional AT motherboard.  As of this minute, the Red River
AT motherboard is the only one with an XT form factor.

I haven't tried this personally, but a board is on order and I should
know more in about a week. The results of my trials and tribulations
(if any) with this board will eventually be published in PC magazine,
so you can get more information there some time "not too far off, now."
