You hook up SATA power to the back of the drive connectors. (I’ll eventually need a 4th one when I fill the cages out to capacity at 15) These cables are great because they are compatible with both types of drives. I used 3x Mini SAS Cable with SATA Power, SFF-8087 to SFF-8482 Cable to connect my mixture of SAS and SATA drives to the HP Expander. Then I secured the motherboard followed by the PSU. I used a piece of paper and a mechanical pencil on the bottom of the motherboard to map out the stand off locations so I could use it as a template to adjust the stand offs in the case. With the drives installed in the cages I went to work installing the PSU and OTiS. Doing so allows me to work on drive swaps later with much more ease so I don’t have to remove the entire cage to swap out single drives, etc. But I chose to ignore that instruction and just leave the sleds attached to the HDDs via the plastic pegs alone. With the L4500 it comes with screws and instructions to tighten screws securing the sleds to the HDDs after they’ve been inserted inside the cages. Upon realizing my mistake I flipped them to the correct orientation and was back in business with 5 per cage. Again with the classic Taco derp moves, I initially sledded up my first 5 HDDs and inserted them into the cage upside down which only let me do 4 per cage. I was having a hell of a time until I realized I was attempting to remove them in the wrong direction. Tip #2 I learned: When removing the drive cages don’t be a dummy like me and attempt to remove them by pushing the tabs on top and pulling them rearward in the direction of the inside of the case. You only need to remove the front screws that hold the fans in place and then you can reach in through the back of the drive cages (shown above) to move the now loose fan a little to the side so that you can pull one side in at an angle to then remove the fan all the way through the back. Tip #1 I learned: The cages don’t have to be removed to get the front fans out. I actually had this sitting out in a bare-bones, caseless configuration on top of my PC case for about 2 months before embarking on the hybrid project. PSU: EVGA SuperNOVA 750 G3, 80 Plus Gold 750W, Fully Modular.Motherboard: Gigabyte H370M D3H GSM micro ATX. I came to the conclusion that the best way to achieve all my goals was to use a Rosewill L4500 case as a DAS and to house a micro-ITX based OTiS build as a quicksync box in the rear of the case while borrowing the PCIe slot on the OTiS motherboard using a powered mining riser to provide power for the HP Expander giving me the DAS to NAS connection.įirst I needed to build out the OTiS.
