B660 Gaming X in any of its variants (ATX, mATX, WiFi, non-WiFi, and any combination of those) is probably your best bet then. Solid VRM, BIOS flashback (or more accurately Gigabyte's version called "Q-Flash"), and a pretty good feature set. The B660M-A Pro does have the better memory topology if you want to run high speed DDR4, but at the same time if you're gonna be getting a high enough speed kit to where it would make a difference (>3600MT/s), you really should be going for a kit of DDR5 instead anyway, so that doesn't really matter. 

It's mostly just an aesthetic difference, so it's up to you. The ATX revision does have a couple extra things (an extra M.2 slot and slightly better rear audio from the looks of it), but nothing whether the aesthetic difference and the ability to run 3 NVMe drives instead of 2 is worth the extra money. I probably would spend it, but that's more because I like really big cases where mATX boards look really out of place than for anything else. 

Does anyone know if refurbished laptops are cleaned at all, specifically open box/customer returns laptops?
 
I don't wanna get a laptop returned by some dude who used it for watching porn and touched it with his jizz hands.
