Thank you for the offer, I am intrigued but have no funds at the moment I'm afraid.
I bought [USER=130]@CC Ricers[/USER] prototype MT4s case and have bought a load of kit to go in that, and that has left me with no PC money. Sadly shipping was expensive and paying VAT bumped things up.
If anything, I should be selling my H81T and Q87T boards, as one has been replaced by a NUC, and the other was a spur of the moment purchase as I had the CPU / cooler / RAM / PSU all in the parts drawer. That did make for a cheap build that has mostly sat unused in its box.
Merci [USER=55]@GuilleAcoustic[/USER] , I had a quick look at that possible wrinkle and it seems OK.
I know that on larger boards M.2 slots share resources with PCIe slots and SATA ports.
Asus are saying on the Q87 web page that the Mini SATA and Mini PCIe are the same slot and cannot be used at the same time, but there is no mention of a conflict between mSATA and SATA.
I will consult the manual next just to check.
