The UP1000/UP1100 aren't even nice on paper. What makes them borderline
interesting, is the use of AMD chipsets, but the benefits of that never
came to fruition. The UP1000/UP1100 are very memory limited, in size as
well as in bandwidth (max. 768MB, single channel SD-RAM). The UP1500 on
the other hand is much more useful in that regard (up to 4GB DDR266).

I don't think so.

The UP1500's AGP port is a bit... special. Don't expect wonders from it.
If I had to chose a decent system, it would probably be a DS10 or, if
you can get a hold of one cheaply (yeah right, haha!), a DS15.
The largest I'd go for a hobbyist system, is a DS20E, DS25, if you
can live with them consuming ~500W doing nothing.
