server motherboards don't care what size the drives are, that's a 
function of your server *chassis*.    You can always put a 2.5" drive in 
a 3.5" adapter, but many modern servers are designed specifically for 
2.5" drives, especially servers using SAS.

example, note the two servers on the top of the closer rack.

those are HP DL180g6, each holds 25 2.5" SAS hotswap drives in a 2U form 

I *do* recommend getting 'enterprise' grade SSDs that have 'supercaps' 
to ensure they can flush their write buffers on a power failure.
