The tower's dimensions are:
height 26,6 cm
depth 40 cm
width 18 cm
With devices, it all weighs around 10 kg.
It's got a 250W power supply. Internally, it takes 50 pin devices.
There's an external terminator.
Besides the Zip drive, the HP CD writer and the Plextor CD drive shown in the pics, it's got a 6.4GB Quantum Fireball HDD formatted with SFS or PFS (I can't remember which) and currently empty.
All drives are recognised on my A1200. I haven't burned a CD for a long time though, so I am not sure whether the CD burner works 100%.
The 5.25 to 3.5 adaptor the Zip drive is in at the top of the tower is a bit weird. I had to put screws in odd locations. It will probably come loose during transport, so I would have to take it out before packing.
I will also include several blank 100MB Zip disks as well as some SCSI cables and the power cable.
I am thinking of 150 Euros plus shipping.
