#3 Unable to verify if ECC is functioning or not
Latest status: On Xeon P50/P70 with ECC RAM, hardware detect software showing ECC as "supported, disabled". While the same software shows "supported, enabled" on other machines.

Also, compatibility with faster RAM. Users want to use 2400 DDR4 not for speed but for availability:

#5 Unable to find RAID option in BIOS
Latest status: More of a sales strategy other than a technical problem. You'll have to choose the RAID option while placing the order. There's no way to add RAID option after the product is shipped.
#6 "display driver stopped responding" error on Windows 10
Latest status: This is more of a Windows 10 / display drivers issue. Seems to happen on Intel HD display card only. Suspect RAM related (as Intel HD use computer RAM as graphic RAM).
Suggestions for P51:
1) Keep the two 2.5" bays but make them support 9.5mm HDDs. Actually, you can squeeze in 9.5mm HDD into P50 if you trim down the "teeth" on the backcover. Since the chassis is thick enough for 9.5mm HDDs why not make it easier for customers?
2) Make both 2.5" bays support M.2 drives, so we can have up to four M.2 drives. With four M.2 drives, RAID5 becomes possible (Skylake CM236 chispet already supports RAID 5). That would be really a killing feature!
3) If possible, build the 2.5" interface onboard to eliminate the needs of cables. To keep the bay multi-purpose (supports both M.2 and 2.5" form factor), consider putting the M.2 interfaces on one end and the 2.5" interface on the other end.
4) if possible, make the 2.5" interface SFF-8639 (U.2) compatible so it can support PCIe 3.0 x4. SFF-8639(U.2) device end is backward compatible with SATA.
