It may look good on paper but ASRock? No thanks. Too many boards that promise a lot and end up either being not fully functional or buggy as hell. Then in short order stop making BIOS updates leaving the thing to rot. Many defunct motherboard manufacturers operated this way and they eventually folded because of it.
My primary criteria when looking at board makers is to simply look at how long they continue to support the board with updates over time. Some manufacturers simply crank out a board then abandon it for the next one. These seem like poorly run companies and a recipe for disaster.

My go-to board vendor these days is Supermicro, as they seem to make a solid product and will still release BIOS updates years later. I have a bunch of H8SCM Opteron boards from them, circa 2011, and they most recently shipped a new BIOS in 2016 - a full five years later.

I really like the design choices for this board -- however, I would like to add other cards -- another reason why I'm looking at epyc. While the board is designed well enough that I can put 4 dual slot GPUs, that will probably leave the x8 slots blocked. Unfortunately as far as I can make out, the only single slot GPUs are sub 100$ or those over 800$(water cooling).- I would like to know if it is possible to use all slots.
- Also I would like to split 1 or 2 x8 slot into x4 or smaller.
Will this work? also what should be the length of the extension cable to clear a full card. I do not think risers alone will be tall enough, and to best the best signal integrity with a passive cable the length should be minimized.
Examples of risers I have seen are- supermicro RSC-R2UU-2E4R= (2) PCI-E x4 in PCIe x8 slots
- supermicro RSC-R2UW-2E4R= (2) PCI-E x4 in PCIe x8 slots
- supermicro RSC-GR-A88 active = (2) PCI-E x4 in PCIe x8 slots
