NEW to WYSE thin client

NEW to WYSE thin client

I just picked up a C90LEW WES 1G from Boarders, because they didn't play the economics game, for $7.50. Yes, you read that right.

So it didn't come with a PSU, so I found that my linksys router spits out 12v at .5A max, it powered on, went through the boot cycle of XP pro, then a flash screen of KOBO came up then it shut down. It does not have a wireless card, and I did not have it connected to a router. What can I do, I just downloaded the suit of PDF's and image updates from wyse, but I don't know where to start. I am wondering if I start it up connected to the interWebs it will try to connect to Boarders...

So what should I do?
Find a compatible PSU, because WYSE is currently out, find one at radioshak that spits out the correct amps and what is the Correct amperage?

Flash an new Image?
Update/upgrade bios?

Install new mem from the 1GB?

I'm lost help me
