Rosewill RSV-4310 - Useful Revision To One Of The Best Value 4U Server Cases

Sun, 11/24/2019 - 04:17
Over the years at Phoronix we have easily close to forty if not more Rosewill 2U and 4U sever cases... Rosewill's server cases have been among the best value enclosures when not needing any extra features like hot-swap bays, etc. For under $100 USD, their Rosewill 4U cases have been a favorite due to the cost yet good quality, fan filter, etc. A new revision out this summer is the Rosewill RSV-4310 that appears to have replaced the likes of the RSV-R4000. The RSV-4310 4U enclosure does bring some nice minor updates to the base enclosure we've come to know and appreciate though is more costly.
