Upgradable Tower PC (i5/i7 12th Gen) for 3D Printing (Capel St Mary IP9)

Hi everyone,

I am looking to take my first steps into 3D printing and design, but I am in need of a capable computer to run the slicing and modeling software.I am looking for an older business desktop or engineering workstation featuring an Intel Core i5/i7 processor (10th/12th Gen)

Ideally, I am looking for one of the following models (or similar):Dell, HP, Lenovo or similar because I need to add a dedicated graphics card to the system later, it does need to be a full-sized tower.

If any local businesses have recently upgraded their office IT systems, or if anyone has an old machine sitting in a cupboard or garage, I would be incredibly grateful for a donation.

I am more than happy to make a charitable donation to a cause of your choice, or offer a token of appreciation in return.(Note for data safety: I am completely fine taking the PC without a hard drive, as I can easily install my own.)

I can collect promptly at a time that suits you.

Thank you so much for reading!
