If you type in RMC4D in google you find some more companies. The
manufacturer of this chassis seems to be Anova.

This all is mentioned at the description. I wanted to use only 12 of the
disk for data with two promise SX6000 raid controllers. 2 others would
be mirrored system disks and 2 slots could be used for regular DVD-ROM
and Floppy.

That's bad. On the other side it shouldn't be necessary to replace the
disks very often.

May be you should use round IDE cables.
The problem is that there are no many alternatives for such a case if
you want to have a compact all-in-one server combining DVB-server and
file storage. I want to use at least 12 disks for Raid5. Regular cases
don't have enough slots.
Alternatives are:
- use normal PC and extent with Firewire disks
(expensive, large, software raid, complex to handle)
- use normal PC and extent with network storage (Ethernet and Fireware)
(expensive, large, power usage)
Any ideas?
