Emmabuntüs is asking for 64bit PC donations. Without saying 64bit, it is subtly obvious since PC manufacturers. worldwide, adopted the mandate for 64bit PCs, fully, in 2007. The only exception since was Netbooks in the years since.
If you reside in the EU, they will repurpose discards.
The PC donation centers I worked with stop accepting 32bit PC, few years ago as their shelves are stocked with donations waiting for requests from disadvantaged or non-profits assignment. So they limited the intake to only 64bit PCs almost 5 years ago for a number of reason including lack of shelf space and demand. They also significantly cutback on VGA acceptance as well, now that PCs have DVI/HDMI/DP connectors.
