Its a sama lo1, bought it locally, its supposed to have 2 2.5 slots but it isnt a normal case, i cant see whereThe SSD as far as I can tell is a 2.5" size one.
You don't mention what case you have. Generally you'd either need an adapter to install a 2.5" drive in a 3.5" HDD cage slot, or the case has adapters where the SSDs can be installed behind the motherboard. Then there might the need of screws depending on the case as well.
Then there could be the extreme scenario if the case is so small there's only space for one drive.
