Absolutely! Any reasonably-sized PC case (IE: AT/ATX, not ITX) with six
or more card slots will hold an Atlas populated with six of the largest
100 by 220mm cards.

This is a very good option for some users of the HPSDR. I believe one
reason the Atlas design chose an 0.800" center to center card spacing is
to accommodate the use of a PC case as an HPSDR case. In addition, it
already has a power supply! Shielding may be a concern - I've seen some
lousy shielding even in good quality PC cases.
There is a gentleman here who even has a webpage with a drawing of the
HPSDR fitted into a very fancy PC case. It's very, very nice! I dare
say it's art museum worthy - like a very fine piece of high-end stereo
gear. I can't seem to locate his message with the link, so hopefully
he'll respond and share the link to his page.
For other users with limited space or those desiring portable operation,
a PC case is simply too large and bulky. An AT/ATX case with six slots
is fairly large with much empty space inside. Or, better said, I've not
been able to find a rather small PC case that has six slots in the rear
that doesn't waste a lot of space. Many, including me, just don't have
room in the shack for another computer sized box.
Pandora is meant to be both a solution for this smaller case need, as
well as provide a buffet of parts for those who, say for instance, want
a rack-mount HPSDR. To me, one of the wonderful things of the HPSDR
concept is that each of us can choose the case we want, the cards we
want, and I'm probably jumping the gun in saying this, but also the
software we want.
HPSDR - have it your way! My apologies to Burger King. (I wish we had
a good Burger King here, but alas, they are all awful.)
thanks much,
