The board fits anything that is standard mITX form factor. All the I/O will fit in a standard ATX rear opening. For height clearance on a 1RU case you will need a custom low profile heatsink and fan. The stock heatsink / fan needs about 40mm of clearance. That Silverstone case you linked to will not work as that is designed for Thin Mini-ITX which is a different standard. However something like this Chieftec case will work fine. IX-01B-OP-Chieftec
