Now need to find a case for it and some space :)
What are my options regarding the case? Any known substitutes? Big tower maybe? Anyone has experience?

This tower looks great! Not sure about my skills on the metalwork though...
I guess I would settle on standard case if I could find one but will keep my eyes peeled for a big AT tower too.

Hi,
So the resurrection is progressing but not without issues. I managed to fit the board into the case and happily boot from Ultrasatan.

I can run Mint and Geneva but I have few issues and maybe someone can help?
Main one is SCSI which is probably not unusual after reading few posts. I tried attaching external SCSI but it is not visible and what’s worse HDDRIVER will not run but crash. I run diagnostics cartridge and it fails on SCSI test:

Other than this I have odd issues in Mint like Tos2win crashing etc. Geneva seems to be much more stable.
Any suggestions?

Make sure your terminations are correct. I think you need to terminate the external device, but I'm not 100% sure whether you need to remove or keep the internal termination resistors... I always forget, maybe try with and without to see what happens. Always run an 'auto-configure' in hdr-util after each change.

I have no terminators inside - do I need them without any device attached? I would imagine HDDRIVER should still run? I can run HDDRutil but little point without the driver?
