VIA machines are not the cheapest. But they are quite popular, and one 
of the reasons is that they are easy to use (read: fairly well supported 

As a beginners thin client I'd recommend either an old one, like EPIA 
ML6000EAG or one of the cheapest of the newer ones, like EPIA 

Even if the newer one is more expensive, the RAM might be cheaper for 
that one. Especially if you want larger RAM, to experiment with running 
as a "half-thick" client (running diskless but executing some or all 
applications locally).

JrSX lack FPU. Jr has one, I believe.

JrSX was reported to not support PXE - but possibly support other 
automated LAN boot methods like RPL. Jr may support PXE, I don't know.

I am not sure if I understand your question, but I will try...

VIA Epia is a series of low-power all-in-one motherboards. Some of them 
are underclocked and the CPU fan is replaced with bigger pasive cooling. 
Some of those fanless motherboards are rebranded as "VIA Epia", some of 
them labeled with a capital "E" in the name, while some are simply sold 
as "VIA EPIA, without fan".

I buy a motherboard, a RAM chip and a case. And boot with PXE. Works 
fine with official Debian kernels (older ones with 486 kernels, newest 
ones with 686 kernels).

The motherboard shape follow a semi-standard called Mini-IPX, but fits 
into standard ATX variant cases soot, so cheapest solution is to use a 
standard case, but more elegant (and expensive) is compact cases like 
the compact Morex 3688[1] or the more flexible (read: can fit a 3.5" 
disk) Morex 2688 and Travla 138. That last one is my current favorite.

Search Google or your local (well-assorted) computer dealers for "itx" 
to find both motherboards and (if you want that luxury) custom cases.
