You're welcome, there was a Q87T frenzy a few months ago, as they was a batch of bargain BNIB ones on UK ebay which the Bit Tech SFF boys joined in on.
I have just looked at the Q87T SATA power cable, and it's very odd...
There are 5 SATA connectors on the included SATA power cable PLUS what looks like a SATA data connector with red and black wires attached.
I can take it out of the bag and photograph it if you like.
**EDIT** Here's a link to a sold one on ebay with photos
I would have thought that 4x 2.5 HDDs would be fine; 4x 3.5 probably not on start up. Without motors, I would say you'd be 100% fine with 4 SSDs on that setup.
The board has an mSATA slot, so you can boot from that and still have 4 storage drives.
One of the guys on B T is selling his lightly used Q87T for under 30 GBP...
Having not done so, I am still tempted by a using brickless 19V power solution so that I can use the internal power header that has been unused on at least 4 of the thin ITX boards I have owned. (DH61AG / H81T / Q87T / H110T ).
