3 basic working midi-tower PC base units (Kensworth LU6)

I have 3 basic midi-tower PCs which would make great projects:
- 2 x Intel Core Duo
- 1 x Fujitsu with an AMD processor
- all three are checked and working
- all three have processor and RAM
- all three have optical drives
- they all need a hard disk or SSD as I've removed them for secutiry reasons
- I have some spare hard disks to get you going but you'll have to put them in yourself
- you'll need your own mouse, keyboard & monitor but I have a couple that I'll be putting on eBay if interested

They were all donated to me for refurbishing & re-gifting but I have now given up working on desktop machines due to arthritis. There's nothing wrong with them apart from the processors being inadequate for Windows 10. However, they will run ZORIN OS16 very well - Zorin is a Windows-like Linux distro which works well on older machines, and is complete with an Office suite. Very simple to download, install and use.

Available for collection most daytimes up to 6pm. I'd like all 3 to go together please.
