Hi Nelson,

Further to recent correspondence, I'm *very* pleased to say that my attempts at building the Aleph4 have been successful ;-)

I had to do this in "semi-budget" mode, so acquired most of the power supply and heatsinks surplus. Was lucky enough to find some 300 x 360mm heavy duty sinks which were perfect for "sides" for a tower-style case. 

Had a lot of fun doing this. Was the first time I had ever designed or made PCBs and they worked really well. I got inspired and even made boards for the 3-FET sets!

Heatsinks are perfect ..... its been running for 4 hours and the sides are hot, but you can leave your hands there for a reasonable period.

Once again, I am stunned and grateful for your open approach to your intellectual property.

BTW ........ sounds great too !

Cheers

Mark Finnis
