Vortex Sound Research

I'm looking to take the plunge into Eurorack and have been hung up on which case to buy. I found this one-man operation (?) that sells on Etsy and Reverb called Silvas Modular Cases and the HP per dollar rate seems pretty unbeatable for non-DIY, outside of the Mantis, which I'm not super interested in. I'm particularly looking at this 9U 104 HP Studio Case for $510 + $48 shipping linked below, but haven't seen much on here/MW/etc about Silvas, only about twelve Reverb reviews that are unanimously five stars. Does anybody here have any experience with these or at least an opinion based on the pics/specs?
