Socket 775 are mostly DDR2. That socket went EOL 2009 or so, so I cant imagine many manufacturers implementing expensive DDR3 (at the time) on an old socket. The dell is most likely DDR2.
Honestly forgetting about the money spent on the QX, on the bay 2x 1gb ddr2 is selling for about £12.
As to the 560 case couldn't say. Dell used to use their own proprietry motherboards which had their own custom form factor. Whether they still did this at the time you bought yours I don't know.
edit: the manual may say.
