Things somewhat improve the last two years.
Due to the propagation of the Internet people are more educated and less
inclined to buy junk-yard PCs.
A good indication is the number of AMD suppliers.
The first time I bought an AMD CPU (K6) I had to order one from the U.S.
When I got the K7, I needed a special order. 
Getting an Athlon MP was a bit easier.

Last week I ordered two Opteron 270 (a workstation chip) and I got it
within two days.

Either that, or Live Linux CDs. (There's literally hundreds of them.)
I couple of good options:
Damn small Linux. Full Linux in 50MB http://www.damnsmalllinux.org/
Knoppix: The father of all Live CDs:

In general, the bigger the fan the lower the RPM required to keep the
CPU/case cool.
When you ask for price quote, ask the vendor to use big (and slow) 120mm
fan for the case and at least 92mm fan for the CPU.
More-ever, as the vendor to use a brand names fans.
E.g. Thernalright, Thermaltake, Sunon, CoolerMaster, Vantec, Zalman.
