Z390 mainboard for OC

[white_dove]

Hello everybody,
I'd like to purchase a mainboard, my CPU is I7 9700K, OC@5 Ghz.
Right now I'm using the Maximus Hero XI but i want to get back to Gigabyte
What would you recommend for OC / gaming ?
I would like as many as possible USB ports ( rear case - external )
Mouse, keyboard, joystick, throttle, pedals, TrackIR5, USB stick for Xbox gamepad, external sound card.
Does the USB DAC UP 2 would help for my Creative X7 external sound card ?
I'm using 3 X SSD and 2 X HDD plus 1 x DVD RW.
Maybe in the future I'll add another SATA SSD or M.2
One more question, please : if there is no more sata port, in case I'd go for another SATA SSD, could I buy a PCIe card ?
Something like this ? Would that work ?

I think i go with Gigabyte Z390 AORUS ULTRA
But I have a question :
what does it mean F USB1 and F USB 2 ?
Could I use my external HDD ( 3.0 ) on the case - front USB ?
My case is Thermaltake Chaser MK-I

If you have decided to build your gaming PC using Z390 motherboard, then better to know the reviews and features of this product. Gigabyte launched the latest Z390 motherboard that is multi-dimensionally efficient to provide you with comfortable computing. I personally suggest to go for the Aorus Ultra is a Z390 motherboard that supports the latest processors like the Intel Core 8th Gen and 9th Gen. Thus; you can easily assemble a smart PC setup.

I purchased the Aorus Ultra, I'm trying to OC my CPU ( I7 9700K ) right now
Is there no Clear CMOS button ? BIOS reset button ??
Thank you
