[hpsdr] Mechanical considerations for ATLAS cards

[Alex]

(a) it forces me to fabricate a new mounting plate for ATLAS that is perpendicular to a perfectly good mounting bracket on the bottom of the case
(b) I still need a bracket for the external connector. Now in order to swap out the card I have to remove the entire ATLAS assembly in order to remove a card, since the insertion direction for the card into the ATLAS is perpendicular to the insertion direction for the external connector bracket.

So I stand by my statement of preventing me from using any computer case. I didn't say it was impossible to use the case.

If somebody wants to make a minimal-size HPSDR/SDR-1000 configuration you just grab an old surplus pc case, remove a section from the front half of the case and reattach the front plate to the back half of the case (like chopping down a car). Or just cut out the rear expansion slots section of the case and use it in your own from-scratch box.

Or buy one of the cheap mini cases and mount everything in it - less time and hassle.

Plus the added card size gives more room for increased funcationality per card and thereby reducing the number of cards in the system (since we seem to be getting more cards than we can fit on a backplane). 

Don't get me wrong, I think it's a good thing to have more functionality. Keep thinking of ideas for cards.

Not if ATLAS is perpendicular to the bottom of the case.
