Last time I checked, you could get two or three Solarflare SF7122F or Chelsio T520 (-BT for copper) for that money. There are plenty of cheap unmanaged, and sometimes even managed, no-name switches in 4x2.5G + 1x10 G or 2x10G in all configuarions of SFP+ and 10Base-T: Just perfect to plug in a NAS and a MacStudio in 10G and the rest of a little home network in plain 1G/2.5G.
X550 is the best (sole) option if you want plug it directly to 2.5G/5G copper—which you don’t have to do.
There are plenty of options that are way cheaper than interestringly-prices Supermicro parts yet more reliable than consumer-grade Aquantia (and even cheaper too!).
