Hello Wojtek,
this is the nicest Mackintosh setup I have ever seen.
This encourages me to look for a similar setup.
Especially the cast look fantastic.

But I have one question - the slot I see on the 2nd picture - is that for a CD-ROM?!
Though this might be an outdated type of storage device, it would be nice to have it especially on Hackintosh.

Thanks for sharing.

Best Regards, Markus
