Thanks for the help.
I actually wasn't serious about putting the 500 board in the 1000 case. But maybe i'll have a shot since there is so much that can/will go wrong
I would probably prefer the 500 case anywho. I know someone who has one stuffed on a shelf collecting dust he may be willing to donate to me so maybe i'll try the ram in it (just have to raise the case off the ground a bit) or maybe i'll see if agnus will transfer?
