Thanks ZX1Cruizer, sadly not, it would have been perfect but the Intel D945GSEJT has a male 4-pin Molex connector on-board, so I require a splitter with a female 4-pin Molex, and haven't been able to find one
Email back from LinITX in the UK:
"Due to Intel changing the Molex power connector on the D945GSEJT to Male
on the latest batch, you will need to use the power cable included with
the Board and use our adaptor RB413 to convert one of the Molex
connectors to SATA."
So Intel changed the spec...
