This probably won't explode as much...

I actually ran it off the bodged together power supply at the bottom of  the pic for a few hours, the regulators and/or inductors got hot enough  that you could smell them from outside the case, and there's a module  that does +-12volts, with a resistor on the positive rail, as I was only  using the negative rail... There's capacitors on the bottom, fake  Rubycon most likely

The  final design above still isn't the final, one regulator isn't soldered  on, as its the wrong part, and I plan to run bigger inductors all round,  so I'll finish this board, make sure it works, then build another (I  etched two already)

Looking might fine there :D Will be nice to see the final one installed in the case! Are you or have you planned on removing the Amiga square power connector? Keep up the good work :)

I'm going to leave the original power connector in place.

It makes it very easy to measure the internal power supply rails if needed, or run external devices off the internal power supply (the 12volt section is designed to be able to give 5amps, while the A600 needs less than 1amp on this rail, from memory)

I still need to put the VGA connector in place of the RF output, and relocate my SVideo connector to the composite output location :hammer:

ACA620, with heatsink, overclocked to 25Mhz.
Internal slot load CD Rom drive.
A604 and Indivision ECS.
Internal DC-DC PSU (will happily do 5volts at 5amps, 12volts at 2amps)
4gb compact flash card.
Still has the original floppy drive too!

Looking good mate! :)

Is the ACA running stable at 25MHz with the heatsink?

As yet, I haven't run it for an extended period.

With the power connector were I've put it, the lid won't fit on :P

I've got some cheapo thermometers on their way, as I want to keep an eye on the PSU, and CPU temperatures the first few times I run it, with the lid closed.

I was also considering adding a fan into the top of the case, but I'm not sure how much this will help...

Personally I'd use a fan if that was my rig. Even a slow fan will do as it will move at least some air about. There's a small space to the left of the floppy where some heat vents remain. I'd probably rest it in the case at 45 degrees, drawing air from the vent blowing it towards the front. If the cpu does get hot, then just put the fan anywhere... As long as the air flows towards the heat sink.
I have a fan in my A600, as mine has a ACA630 which in my mind is too warm for comfort without the fan.
