The only downside would be struggling with 8GB, which should be upgradable just as well. 10y old would have a cd/dvd tray - that can be replaced by an SSD for 4TB of goodliness (SATA but still good enough).

My spouse has a 12y old laptop that has had pretty much everything (but the soldered GPU) upgraded - CPU, memory, HDD->SSD, CD-SSD, WiFi (to support 5GHz), keyboard (replaced), fan & heatsink, battery (replaced, might rebuild one w/ LG's 18650 MJ1). Unfortunately pre-Sandy Bridge memory is capped at 8GB, so it shows its age - still an amazing thing.
