Yes. 3670 supports 3.5/2.5 hdd. you just install the M.2 ssd in adapter and install the entire module as a 2.5 sata drive like a 2.5 hdd. Install OS on it like you do on hdd. It will boot.
I try to intall an m2 sata  ssd 128gb ( SAMSUNG PM881 M.2 128 GB SERIAL ATA III 3D TLC NAND NVME) but i cant. The disk is not working at this pc. I thik this is because it is sata III and not pcie. Is there a way to make it work (with an adapter or something);
