You could repurpose the mSATA into an Intel NUC 4th gen or sell it ofcourse. Also possible is putting it into a 2.5" adapter. mSATA has had a short life, basically because it took to long to reach adoption and it's quickly being replaced by M.2. Still not as short as SATA Express though But M.2 is still an issue, since there is only one Z87/Z97 mITX board that offers the full speed spec (PCIe 3.0 x4 with NVMe and >80mm length) and that is the Asus Maximus VII Impact board which retails about double of the other mITX Z97 boards.
I would definitely look at the Asus Z97I-PLUS as a good alternative. It supports the Samsung XP941 after a BIOS update: http://hardforum.com/showthread.php?p=1040937477#post1040937477
yes, i was thinking of getting a mSATA to 2.5"-drive adapter and just use it just as a regular storage drive. i think that'd be the most cost-effective solution, given that i have to buy a new motherboard as well; that just adds to the cabling mess though, but i know i won't be buying an M.2 drive. there is also this or this mSATA to M.2 adapter which might be useful, although i'm not if it'll actually work and if i'll be able to boot off that drive.
