I have a friend gifting me an i5-9600k as an upgrade from my aging i7-4770. So I am in search of a decent but not super expensive Z390 board for it. I don't know if I'll bring my hardware RAID card over for scratch drive use or not, but I'd like the option if I can. Please save me from the best deal I've found on eBay of a HP OEM (but somehow still standard MATX form factor board) Z390 board.
