I have looked into the slim ones as well, I would avoid them.
I tend to stray from compact, when it comes to heat failure of electronics.
but anyway, it will fit if it's a 2.5" disk, and if not it's probably a 3.5" and even then it will fit a desktop which is 3.5. But most of the resellers have opted for the 2.5 anyway, because they can sell it to desktop owners with an adapter bracket, and sell it to laptop owners, as-is.
I just saw a test on the life expectance of SSD, and there were only two that did not fail prematurely (test done in this last year).
one was Kingston hyper X,
and the best was
the Samsung 850 pro SSD.
but even if you want to go with the one you mention, that's fine, just make sure it has a warranty to cover premature failure.
for myself, I like the samsungs 10 year warranty, but the tests are clear that the Samsung 850 will outlive 10 years for sure of normal use.
probably more like 100 years.
anyway,
peace.

Now originally I mentioned the Samsung 850 pro with is too new to have a lot of reviews, but seeing that Samsung has hit several in top 10 in recent years with 840 pro, and EVO versions, we should not expect less.
but regardless, Samsung changed the warranty from 3 years, to 10 years with the 850 pro.
so they are very confident in it.
here is a review of 840pro, versus 850pro:
the older 840pro being sold out and less product meaning more cost:
http://ssd.userbenchmark.com/Compare/Samsung-850-Pro-256GB-vs-Samsung-840-Pro-256GB/2385vs1408
but again you can go with slimline OCZ vertex (rated #1 a year or two ago on toptenreviews.com)
which is the cheapest yet.
but as far as longevity, we don't know.
especially with the problem of 2D flash on SSD's
(the problem most are ignoring)
Kingston and Samsung are addressing the issue for sure.
it's just that Samsung is giving it's product a low price and a 10 year warranty.
so I am settled on it.
it's good enough for mylifetime
but if you are looking for server quality then I would email:
HGST.com as they pioneered drives that address the flash issue of 2D, and other R/W premature failures.

(NOTE: some new laptops have a 1.8 not a 2.5 but only when they come standard with an SSD drive. Not sure if your MSI one does or not, I searched the home page of the MFG, and they don't specify the smaller rarer size, so I am assuming they are 2.5 inch like most laptops
but regardless, email them:
http://www.msi.com/about/contact-us
put your part number in there, and the drive you want, and ask them.
when it comes to paying high prices for performance, it doesn't hurt to verify.
