Wow Andrew, that looks fantastic! Those are some pretty large boards on the back, must be quite an investment.

Looking at the frame, this thing is going to be huge! Can't wait to see the rest.

Are you sure? yes | no

Thanks Dave. Cost isn't too enormous, since the prices out of Chinese board houses are pretty reasonable. But yes, it is going to be big, and this is basically a toy computer. You can see why mainframes used to fill rooms (and even buildings)!

Are you sure? yes | no
