Regarding Wikipedia's need for a new server: I spoke with my boss to see if my employer would be willing to make a donation. He agreed to let me donate one of our older PCs for Wikipedia:
Dell Optiplex GX100 Celeron 433 mhz 20-gig Maxtor hard drive 64M RAM Windows 98 SE
Of course, you can install Red Hat in its place, and upgrade the RAM and hard drive as needed.
If you give the okay, I can ship it to your address ASAP.
I hope this helps.
