I believe that this has been reported before, but I think it is worth mentioning again.
TRCSX has been auctioning empty cases on eBay. IMHO, these cases would be perfect if you are looking for an alternative case for your i-Opener. The current actions are here and here. Obviously, the first auction is the better deal at $12.88 + $13.00 shipping.
I have purchased two systems that use these cases. They are very well made. There seems to be plenty of room for the guts of the i-Opener in the top part of the case. There is also plenty of room for a hard drive and a laptop cdrom drive in the upper portion. There is a mount for a laptop harddrive included. There seems to be plenty of room for a regular sized harddrive.
The base of the unit is designed for a standard floppy drive and a power supply. One may be able to fit a full size CD-ROM drive and power supply into the base. This would be a very tight fit so the drive and power supply whould have to be chosen carefully.
There is also one more of the complete systems available for action here. I have purchased two of these in a previous auction. This is an awesome deal. The motherboard (Advantech PC-5862) alone is worth twice+ the opening bid. One of the two systems that I recieved had a very nice VGA TFT display. The second had a VGA DSTN display which is on par with the i-Opener. The systems have on-board sound and ethernet. I was going to use it for a car based MP3 player, but it is almost too nice to hack apart.
I have no connection with TRCSX other than being a very happy customer. The machines were shipped promptly and were VERY well packaged (i.e. I got what I paid for in the shipping cost).
I will try to answer any questions about the cases or systems if you are interested.
