sometimes laptops need more or less stripping down to change things, other times things are really easy and it's just a case of one or two screws to swap things around.
to straight fit a sata dvd drive in your pc you'd need 3 things.
first a spare sata port on the motherboard, some images to show what sata ports look like on a motherboard :- https://www.google.c...iw=1293&bih=654
second you'd need a sata cable :- https://www.amazon.c...x/dp/B002UUSX5C
third and finally because it sounds like your power supply (psu.) leads don't have a sata connection, you'd need a molex (4pin white end) to sata (black end) adapter.
this example allows you to power two sata devices from one molex power lead connection from the psu.. :- https://www.amazon.c...HM2M3ZY2KQGANEQ
just saw this 2 in one pack while checking the links worked :- https://www.amazon.c...75SGC2MJF2T2SRP
oem just means the part manufacturer will not be liable if anything goes wrong with the part and you'll have to deal with the reseller/retailer and not the manufacturer to sort out any problems with the part. dvd drive in this case.
probably better explanations of oem :- http://www.webopedia...TERM/O/OEM.htmland here https://en.wikipedia...nt_manufacturer
there is no right or wrong decision you can make in my opinion, if you do have free sata ports on the motherboard i'd probably tell them to ship you the sata drive and buy the needed cables (plus when you're feeling brave enough and decide to build your own next pc instead of buying straight from the shop you can use it again in that. i think you've got the bug so won't be able to not build your own next pc. ),
if there's not then you have another decision either just get them to send the oem ide drive. (most parts i use when building are oem parts because they are cheaper.) and fit that or still stick with sending the sata drive but use a sata to ide adaptor for now and you can then still use the drive in your new build without adaptors (ide drive could be used in new build to with an adapter). .https://www.amazon.c...d/dp/B009SO7R0U
in my opinion there are no real benefits or drawbacks to using either a sata or ide dvd drive because the extra speed capabilities of sata ports over ide connections are not able to be utilized by optical drive read/write speeds anyway. (different with hard drives, sata drives are always faster/best option and why the ide connection is old tech and hardly ever/if at all now seen on motherboards or devices.)
just spent more or less 3 days in bed (started sunday) shivering and sweating myself even though i didn't really feel that unwell and still don't except i now have sniffles and a cough as last remaining symptoms of my man flu, so hope you get well soon enough to really enjoy your christmas.
