i was planning on getting a new laptop cheaply for about 500ish
You should plan for what you need, not for what you're willing to pay. If you need a mobile workstation then this 16 inch laptop would be too large and heavy. If you aim for a desktop replacement, then a 13 inch laptop might be too small (docking stations exist, but still ...).
The Framework laptop is a nice idea, though. But to be honest: how often did you change the components of your laptops before? One usually changes the SSD and maybe the RAM or the battery or - if you're really adventurous - the heatpipe and/or the fan. All of this is already possible with most common laptops. If you're unsure, get a ThinkPad.
