H60 Aluminum Keyboard Case 60% Red Customize Keyboard Housing Compatible with wooting Keyboards Rakka 61/64 Mechanical Keyboard

This red powder-coated unibody aluminum keyboard case from Sumgsn is a tray mount case designed for 60% keyboard PCBs that are compatible with the "universal" 60% case design. That includes PCBs designed and sold by Wooting, Rakka, CannonKeys, KBDfans and many others. The tell-tale signs are a PCB-mounted USB-C connector at the back left, strategically placed screw holes for tray mounting and a notch on each end.The case has a single cutout for the USB-C port at the back left. There is no accommodation for a case-mounted USB-C daughterboard.Inside, the case has small protrusions along the sides. Usually these help support the PCB and a gummy o-ring mount. While an o-ring mount is possible with this case, the PCB can contact with the tray-mount posts on the bottom so unless the PCB is screwed down the o-ring experience is not ideal. As a result the case is effectively a tray mount case only. Because o-ring mount is possible, it would have been good if the tray mount standoffs were removable.Speaking of tray mount, the supplied screws are quite short and have a Phillips head. I really dislike Phillips screws here as they can strip rather easily. Care should be take to not over tighten these screws for fear of stripping the standoffs themselves.If you are using o-ring compatible clip-in stabilizers I recommend trying an o-ring anyways. The o-ring changes the sound signature of the case and the result may be a preferable one.I don't have a Wooting PCB but I am using this case with other universal 60% PCBs.The first PCB I installed into the case was soldered and plateless. The feel is typical tray-mount, solid and stiff. I don't mind this as that is the typical side effect of tray mounting. However, there is quite a bit of unwanted hollowness from the case with this simplest of installations. I added a layer of poron case foam and that did reduce the hollowness but the overall sound was still not to my liking.I then installed a 50A durometer CannonKeys Bakeneko o-ring. With the o-ring by itself the case is rather hollow but adding in the case foam things suddenly tighten up. This combination of case foam and o-ring removes the bad resonance, leaving behind a pretty good sounding keyboard.I then tried the same experiment with a hotswap PCB and PC plate with no plate nor switch foam installed. The results were the same. This plated build also benefits from case foam as well as an o-ring for the best sound to my ears.The power coating is ok on the case exterior but there is unevenness on the inside. I suppose that is acceptable given the one usually never sees the inside. The surface is textured like with any powder coated finish.The typing angle isn't published but it is fairly low. I estimate less than 5 degrees. I find that a bit too low so taller bump-ons at the back may be beneficial.The unibody design is pretty basic. There is no provision for a bottom weight to provide additional heft. The case by itself weighs in at only 24.7 oz. A completed build weights just over 37oz.The bottom of the case has chamfered edges that make it easier to pick up from a desk.As with many Wooting compatible cases these days a hand strap can be installed on the left side of the case. How amusing.Overall I think this is an average but well priced aluminum case option for compatible 60% PCBs. There are better cases on the market for Wooting and other PCBs but a more premium case – especially with built-in weights – can run 2x to 4x more expensive. However, a more premium case might offer better acoustics out of the box.
