New Desktop Build

After 8 years I decided it was time to build a new Desktop. I'm retired and mostly living off Social Security so money is a little tight. But I've been saving all these 8 years for this build. So far I have chosen an ASUS X570 ROG Crosshair VIII Dark Hero and a AMD Ryzen 9 5900X. I have yet to decide on Memory, SSD, Hard Drive or cooling fan. My biggest hurdle right now is Memory. I'm looking for 32gig and 3200Mhz or faster but everything I like does not appear on the ASUS ROG Memory & CPU list (https://rog.asus.com/motherboards/r...hair-viii-dark-hero-model/helpdesk_qvl_memory). I'm not into gaming right now (I was 20+ years ago) but I'm ready to get back into the fight. I would be very happy to hear any suggestions on Memory, CPU Coolers, SSDs (Corsair MP600?) and Hard Drives. I already have a case (Cooler Master HAF 932) and power supply (EVGA 850 G2).
