The CyanogenMod team is seeking donations from the community to help bolster the hardware needed to keep things going. There are some 56 devices supported on CM's official listing, and nightly builds and official releases take some serious hardware to crank out. And that costs money. Writes CyanogenMod:

We need to purchase new hardware to take on this task. A couple of solid, stable Xeon-class servers with large amounts of RAM and fast disks. Virtual private servers won’t cut it for build machines.

CyanogenMod is not a for-profit business. We are just a bunch of geeks, trying to make our phones more awesome. The donations we get currently cover our operating costs and occasionally go towards developer devices. This time, I need to ask for help from the community for something a bit larger. We need to purchase these servers in order to bring the build infrastructure back to full capacity.

As such, there's now a PayPal widget at the bottom of the CM site that allows you to donate as much or as little as you want.

Update: And the CM team has hit its goal.
