OptiPlex GX520 – Windows 7 32 Bit

Donations

£1.00

It is not advised to spend too much money upgrading this over a decade 2007 system, as it is cheaper to purchase a more capable Second Hand Business Desktop than a new OS License. This PC can run Windows 7 32 Bit borderline. It does not run Windows 10 very well.
