HP ProDesk PC
It's getting on a bit computer-wise, but could be useful to someone out there.
It has a fresh install of the Ubuntu 16.04 LTS OS, it's not Windows, but anyone familiar with Windows should be fine with it.
4GB RAM, 64bit with an Intel Core i3-6100 CPU 3.70GHz x4 Processor, 490GB HDD.
Please note that this is as shown, no keyboard, mouse, monitor or cables included I will try to find a mains cable before collection.
