[BBC Micros] [Computers ] [8 bit Upgrades ]
Solidisk produced a CPU and Keyboard case for the BBC Micro which was described in an advertisement in Acorn User (June 1986):
"This compact steel case can hold a BBC and two 5.25 inch half-height floppy disc drives. The keyboard is housed in a seperate case connected by a 24 inch lead. With the monitor on top, it improves your viewing angle and leaves your desk uncluttered."
This BBC Micro model B has an Issue 3 motherboard and an ICL serial number. I bought it on eBay in August 2009. It has a Solidisk 1770 Disc interface and a Solidisk SWR256 256K RAM/ROM board.
Here are some pictures:

The back of the CPU case shows that the case only replaces the top of the plastic BBC case. The standard BBC ports are visible, from left to right:
The power supply is on the left.
The cooling slots apove the ports allow you to see the BBC motherboard, this is a sign of an early BBC Micro before they were modified to prevent little fingers getting in. The two screws are missing from the holes marked FIX, the Solidisk CPU case does have matching brackets for them.
