I've got a server up for sale, acquired when I purchased another host a few months ago. My wife is getting on my case to get some stuff out of the basement. I'll let this one go cheap...
Specs are as follows:
1 CPU (Pentium 4 2.66Ghz)
Tyan S2099 M/B
1GB RAM (2 x 512)
80GB IDE hard drive
(2) 10/100 network ports
Promise IDE RAID onboard
ATI RageXL onboard video
Here's a link to a quick page I whipped up that includes a photo...
I loaded Windows 2003 on it for about 8 weeks and used it in production until I got some more of my IBM servers online. The fans are kinda noisy, more than I'm used to with my IBM xSeries, but if it's in a data center, no one's gonna care.
The plastic along the front face is slightly warped but it doesn't affect the metal chassis at all.
The hard drive has been wiped and it's ready to go. I've got a nice box to ship it in so that it will be properly protected in transit. If no one here wants it, I'll slap it up on Ebay.
I'll take $250 (Paypal or credit card over the phone) and include free shipping via Fedex Ground to the lower 48.
