Looks like 1.5+1+1.5+6+1.5+1+1+1.5 .
A little odd layout, but not as bad as Corsair =P
Just some more info:
The most usual layouts here are:
1.25+1.25+1.25+6.25+1.25+1.25+1.25+1.25
1.5+1+1.5+7+1.5+1+1.5
So the latter would suit your board better, but the spacebar won't fit (and you'll have to find another small 1u key).
EDIT: Seems like it's a center mounted 6u spacebar too, which seems a little unusual (according to
DeskThority wiki)
