this is the first formula of a tray-mount build that i like more, compared to other combinations that i have.
i have some unpopular preferences: in short, i want a tray-mount plated build that produces relatively soft, but somewhat stiff, and clean typing feel. (clean means with less vibration when typing) it should not be loud also.
it's always possible to achieve the above with a tray-mount (which is famous of hard spots and stiffness), as long as you choose appropriate parts and mods:

- the pcb is covered with 0.5mm poron switch pads. i have tried xe and eva as well, but poron gives a relatively better softer feel imo;
- plate is aluminum, with 3.5mm poron plate foam. aluminum is relatively softer compared to other options;
- switches is sp-star meteor grey-white, with stock linear rated 57g springs. its full nylon housing give relatively softer feel, compared to pc/uhmwpe/mixed housings. the switch was lubed with mix of krytox gpl 101+205g2 (krytox gpl 205g0 will work fine also), springs lubed with krytox gpl 107, and 0.3mm kelowna mdi switch films were applied (0.2mm poron films should be fine also);
- case wise, it's an old-school generic 60% case with weight. i don't file standoffs. i put layers of anti-slip mats to fill up the space. at the top, i use 0.5mm eva foam to cover all standoffs, including those supporting extrusions at the sides;
- the mounting style is friction-fit with gummyworm o-ring. i use 3.5mm cross-section/thick, 165mm outer diameter silicone o-ring, because it's relatively softer than nbr o-rings that i have; (luckily i don't need to file the usb-port opening, because everything fits nicely)
- key caps, i choose domikey cherry profile sets. thick pbt sets can improve softness, but to me thick abs is just fine;
- stabilizer wise, i use everglide v2 (modifier keys), and equalz v3 (space bar) pcb-mount screw-ins, with epsi mod and 1mm wire supporting foam. they are lubed with krytox gpl 205g0.
this is my last build in the year of 2021. i am looking forward to trying out hpe housings (giantv6), and tx stabilizers, in 2022.
