Server Upgrade. Intel vs AMD for ITX build

[Tai]

So I'm looking at doing a server upgrade and kinda stuck.

 

Currently I have:

2630QM

Advantech AIMB-272 mainboard.

16GB DDR3 Sodimm

LSI 2308 - 8port HBA

Silverstone - DS380

Corsair SFX 600W PSU

7- 8TB Seagate drives.

1TB 860 EVO 2.5inch drive

2 rando laptop drives used for file processing to keep it off the array.

 

 

I'd like to upgrade this to a newer build. Trying to avoid going overboard on hardware and want to keep the DS380.

 

So that leads me to my problem. I need to keep the HBA so a graphics card is out of the question with ITX. This machine does get used for Plex and being able to do transcoding would be nice when I'm out of the house. So I'm kind of stuck between two ideas. Figuring out a way to do headless Ryzen with something like a 3600x Or going with slower Intel 9600k with quicksync transcoding. 

 

I know there is an m.2 5 port Sata card but I haven't seen an amd itx board with 6 sata slots.

 

If anyone has a suggestion that I just haven't seen that would be great. Thank you.
