We've got three options for you. First, there's this HP.
And even though it's $10 over budget, there's this Gateway with a more powerful Ryzen 7.
And then there's your Acer Aspire 5. Depending on the configuration, we service and upgrade these for our clients all the time. We need to know the complete model number, like A515-45-R1BF for example, and maybe we can give you some pointers and make it "cheaper to keep her". It's just a suggestion, but it's worked out for a number of our clients.
