Heres a few pictures of an SE I got in a lot last year. The front case is totally smooth.

Back case looks like ordinary se case. Don't know whats original or swapped.

I opened it up and found whats in the pictures. The power lead from the A/B to the motherboard has been extended and wired directly into the motherboard.

Theres no drives and I get the chequred board when switched on.

Have not tried to do anything with it yet - I have 2 of these and there both the same.

is this just a normal se or can anyone spot anything unusual about it

its added 2 pics of my DIY scsi cd rom drive - don't know why
