Good case, especially when on sale - RSV-L4000U

“ Over all I'm happy with this case, it's good to finally have some of that enterprise gear in a case thats designed to force air over passive heat sinks. ”

Great chasis for ATX rack mounted server/pc

“ A large PC style ATX PSU will likely extend over the CPU socket (I was using a 1600w seasonic); meaning you will have to use an AIO/water cooling setup for the CPU, or at a minimum a 2u height cooler (this is on an ATX MB). ”
