The SilverStone RM42-502 is a 4U server rack chassis first and foremost. Specifically, it is not a storage server rack, but one with computing as the focus. Thus, it can handle every motherboard out there, especially the dual-socket ones. This means you could load the RM42-502 with a dual-socket EPYC board and hundreds of cores while pairing it with several high-end GPUs for a render system. With the 5.25" drive bays, you are then able to add hot-swap storage drives with ease for a complete and potent system of this purpose.
Yes, the default fans are loud, the case is heavy, and some parts have sharp edges. These are the hallmarks of a classic server rack chassis. That said, SilverStone is also gearing it towards users who do not utilize racks but want all that power under their desk, and the ability to transform the RM42-502 into a tower is most welcome in that regard.
Thanks to more consumer-centric features, like the radiator support, an anti-sag GPU system, and USB-C I/O, the SilverStone RM42-502 can be considered a pretty affordable yet incredibly sturdy, no-frills dual-socket system chassis, of which there are not that many out there. Lastly, at just over $200 for a case with full EBB and CEB support, it will be your smallest expense by far when building that dual-socket powerhouse.
