I tried the Wyse 5150SE (I think that was the model) about a year ago. The
problem then was that the only model that supported X was this relatively
high end, expensive model. It booted off an internal flash disk and used a
really godawful stone-age wm (twm, I think, or something of that vintage).
As a result, it looked pretty naff. I booted it with PXE off a central
server and it ran great.
It looks like they've released some newer models since then that might be
I also played with the Sunrays too; they're rather neat, you can plug in
your authentication card, start an mp3 playing, pull out your card,
authenticate to another Sunray and your mp3 continues playing on the other
The downside of the thin clients is they're all bloody expensive for what
they are, it's almost always cheaper to go with a diskless clone. The
upsides are the management features (which really come into their own when
you're deploying over around 25 or so, and are pretty much required for
any deployments over 100 units), and the silence - no hard drive, no cpu

Nothing too great, then. Web pages with Flash might be a problem - I've
noticed they lag a bit when I run a browser remotely at home over

Er, yes. The Wyse model I tried had a 233MHz processor, I think a Via low
power processor. I've done thin client work with machines as low as 386
SX/16, although the screen update was a problem there. I'd say a 486 DX/2
66 would be the lowest I'd want to go these days, although realistically I
suppose all you'll find at the low end is processors in the 500MHz
The server side is where you'll want to spend the money, dual processor
wouldn't be a bad idea (or quad for a lot of users), plus throwing quite a
bit of RAM at it wouldn't hurt. You'll be better off going for lower end
processors in a dual processor configuration than one big honking
processor. You probably won't need too much in the way of storage,
although RAID of some flavour wouldn't be a bad idea. 100 meg ethernet
should be fine for up to around 10-50 users, depending on usage, then
you're looking at a gigabit switch feeding out to 100 meg switches, and
possibly multiple nics with bonding (so you'll need a switch that supports
bonding - 3Com and Cisco both support it, off the top of my head).
Of course, this is all speccing out assuming you're going to grow with
thin client apps. If you just want to dip your toe in to experiment with a
couple of machines, any desktop machine with 128-256 meg of ram will do as
