Dell Optiplex SX280 SFF with LTSP?

[john]

Hi all,

We're thinking about upgrading some of our thin clients to a used
small form factor computer
with 1G ram and better the 2Ghz processor. We're thinking about Dell
Optiplex SX280 sff
computers which ebay has in lots of 10 for around $150 per. The only
thing I see that I am not
wild about right now is the external power brick. But I also wonder
how sound works with LTSP etc.

I was wondering if anyone had any advice about this particular
computer or has another favorite
small form factor that can be bought cheaply used and in decently
large lots (10 or more).

Thanks for any ideas you have!

John
