Today I have the latest revision of their popular RPC-4020 chassis here. The RPC-4020 is a 4U server chassis with the support for 20 hot-swap drive bays being the main selling point of this model. The RPC-4020 comes in at just over $320CDN - nearly half the price of most other 20-bay hot-swap chassis' on the market. Let's take a look at this exciting looking chassis to see all that it has to offer in the home and professional market segments!
