That would be more than capable. Retro emulation can run on very low end hardware.
But here’s an ebay listing for same model that I bought earlier. It doesn’t include an SSD but you can buy M.2 SSDs for very cheap which I also did. Plus they’re much faster and more reliable than micro SD cards.
It’s very easy to open the machine up which I liked.
RAM upgrades are cheap too but 8GB is a lot for most cases.
A lot of corporate environments use these so when they upgrade you can find them used for dirt cheap, if you don’t mind some possible cosmetic defects. Mine are just stacked on a shelf and I just use them as servers for docker and whatnot.
