the description on www.frozencpu.com says:
"Latest video water block from DangerDen. The MAZE4GPU has a nice copper base with a black aluminum cover. Come with 1/2" chrome fittings. This block is compatible with the latest from both ATI and Nvidia. Does not work with ATI All In Wonder (AIW) cards. "
it looks as though the block will not fit on All In Wonder cards. But will fit on all other cards
