NORCO 4U Rack Mount 3 x 5.25-Inch Drive Bay, 10 x 3.5-Inch Drive Bays Server Chassis RPC-450B

No literature included. 5.25" bays had no mounting system. I did stuff a Corsair Hydro Series H110i GTX 280mm liquid cooler with custom brackets and barley fit in 10.5" video card (because I added CPU radiator). All of this on ATX mobo. Replaced both stock fans for Noctua and added 80mm in rear. I used this for HTPC, and is a very deep case 21.75". I omitted handles and front swing cover easily.*I did not use this as a server case.I would only recommend if you need full sized liquid cooling solution and ATX mobo in this configuration and you are comfortable with basic modifications and light bracket fabrication.Lots of work but in the end I am happy.

Did you build any computers in the 90's? Remember how nonsensical the case designs were sometimes? Welcome to the world of rack mount cases. I wish they would incorporate some of the small changes that found their way into even the most budget of Mid-tower Chassis.Want to change a fan? Get ready to pull a ridiculous amount of screws. Any slight hardware changes are going to take you some time. A few minor designs tweaks could improve the experience... It just seems like most rack mount cases don't care to advance. Case is cloned across quite a few other brands, take the Rosewill RSV-R4000, this is the exact same case. The three bays in the front are all removable and able to be rearranged in any order.

Norco is chaging the design of this case in mid stream, make sure you have the right one. The one I got was not the one in the picture. I am still very happy

I like this case - it's smaller than most, and that's what I needed. However, the description of "Easy drive mounting with 24 screwless rails" is incorrect. This version does NOT come with the plastic screwless rails. Amazon sent me a replacement, which didn't include them either. I called Norco, and they said it's an old description. You have to screw in each individual drive to the cage, which is a big pain. To do this, you have to remove the 5 bay cage to screw it in, thus requiring a full system shut down. It's a cheap case that serves its purpose, but if I would've known about that prior to installing the motherboard, etc., I wouldn't have ordered it.
