MOAR pics from the last arrived - for my pleasant surprise, hard drive just running smoothly, with installed MS-DOS 6 + Windows 3.1. The case is really clean and like new, as well as being ol' style desktop factor - I think I will avoid even to mount the CD-Rom and CF2IDE adapter. TURBO well set up and running, for the most clock-sensitive DOS games (from 33MHz to 16) - I just have to mount (as usual) yet another, and problems-free, SoundBlaster 16:

Unichip 486WB 4407 rev 1.1
SX729 A80486DX-33
Cirrus Logic 5428
MIO-2080
IBM H3256-A3 256MB

I haven't seen before this particular BIOS interface, interesting the option regarding hard disk uilities and testing.
