Well I went a bit OTT and got one of these. It was going very cheap on Ebay though, and I like the fact it has the remote option, this will make it easy to integrate into a safety system.

The mini ITX motherboard turned up and I was able to get that up and running without any dramas, and even though it isn't listed on the Intel website the Q6600 quad core I had laying around works fine with it. The only annoying thing is the parallel port is the other way up, so when I plug my gender changer in it flips the BOB upside down. I am not sure if anyone makes a NON inverting DB25 male - male, so looks like I might have to make up a short cable, or try and make my own instead.

Just waiting for the flex PSU for the PC and the above mentioned 24V PSU to arrive and then I can actually start thinking about assembly.

Regards,
