S-100 systems appraisal

Back in the 1970s and 80s, my brother and I used to frequent computer
swap meets in and around Orange County, CA. We both built S-100 systems
from the boards we bought there. I sold mine long ago, but my brother
kept at it for several more years. Last December he passed away, and I
discovered that he had kept his "big" system, and had put together a
second as well. 
I'm interested to know people's thoughts on what they might be worth,
both as complete systems, which I would prefer, and if sold as
individual components. Everything is located in Santa Ana, CA.

My brother was a fan of OASIS, so his main machine was switch-selectable
to boot either that or CP/M (MP/M). It was almost certainly running when
it was decommissioned (which would have been at least 20 years ago).

OASIS Box
Large (as in washing-machine) enclosure containing:
Four 1/2-height, eight inch floppy drives, in enclosure.
Two eight inch hard drives, probably 10 or 20 MB each, in enclosure.
18-slot CCS mainframe with these cards:
CCS 2805, Rev. D, Terminator/Wallclock (terminator unpopulated)
CCS 2830 Six/SIO, Assy No. 02830-00001, Rev. A
CCS 2832 2 Rev. A, Winchester disk controller (2-board set). Module
9016-Rev02, 7-82.
CCS 2422 Assy No. 02422-0001 Rev. B, Multimode Floppy Disk Controller.
CCS 2066 Rev. B 64K Dynamic RAM, bank selectable
CCS 2066 Rev. A 64K Dynamic RAM, bank selectable
Cromemco 16KZ
Cromemco 16KZ
CCS 2068 Assy No. 02065-00001 Rev. C 64K dynamic Memory
Computer System Resources (CSR) RAM 64D, modified w/external switch(es)
CCS 2820 Assy. No. 02830-00001 System Processor
CCS 2704 Assy No 02704-0000? Rev. ? Terminator Board

The other system is just the mainframe. The manufacture's label is
hidden by the floppies and I was too lazy to remove them to read it.
Black Box
12-slot mainframe, with two 1/2-height 5.25 inch floppy drives (and room
for two more).
Includes these cards:
CCS 2066 Assy. No. 2066-00001 Rev. A 64K Dynamic RAM, bank selectable
CCS 2820 Rev. B System Processor
CCS 2066 2.2K Rev. C 64K Dynamic RAM, bank selectable
CCS 2066 Assy. No. 2066-00001 Rev. A 64K Dynamic RAM, bank selectable
CCS 2066 2.2K Rev. B 64K Dynamic RAM, bank selectable
CCS 2422 Assy No. 02422-0001 Rev. B, Multimode Floppy Disk Controller.
CCS 2805, Rev. D, Terminator/Wallclock (terminator unpopulated)
Konan SMC200 P-SMC-201-A Hard disk controller (no hard disk)
CCS 2830 Six/SIO Rev. C
CCS 2704 Assy No 02704-00001 Rev. C Terminator Board

Separately, he also had:

CCS 2520K Extender/terminator board kit, unassembled, in box with
manual.
Archive Corporation Sidewinder tape drive with two tapes.
Cromemco 16KZ RAM board, with manual

I have photos of everything.
Thanks,

-Nick
