In 2019, released a complete high-end server chassis which served as a dual-purpose chassis for indrial rackmount or high-end home system usage - the RM42-502, main feature being support up to 240mm liquid cooling radiators which was rare to see in server chassis at the time. Fast forward to 2022, is releasing a new server chassis as an enhanced version of the RM42-502 - RM4, with better cooling, greater storage options and most importantly, greater clearance for todays high-end graphics card. The RM44 is designed for space optimization which supports up to 360mm radiators, motherboard up to SSI-EEB and graphics cards lengths of up to 424mm. There is an expansion card retainer in both the RM42-502 and RM44 but in the RM44, there are added mounting holes for an additional 3 x 2.5" or 2 x 3.5" drives; a tremendous and highly functional addition to an indrial rackmount chassis, making this 4U rackmount chassis unparalleled in compactness and space utilization.
