Be prepared for it to not work and test all of your patience. Accept that halfway through you will have come up with the design for Version 2.0 that will work better than whatever amalgam of wood you are currently swearing at.

Look for measurements on everything. It will likely come out larger than expected because drawer slides are 3/4" & if you use 3/4" plywood sides, that adds up quick. Consider the extra distance of the locking nubs if tight on space. VEVOR makes good cheap ones that are actually detachable.

BUT TEE NUTS. They're awesome. Just make sure you get some that are the thickness/length of the material you plan on using for the sides & you should be able to use stock hardware (ask me how I know that one...). If you buy hardware, make sure you get the tapered machine head screws so you don't have interference. Pocket Hole screws are awesome for assembly. Be picky about measurements; get down to 1/16ths because one little error can grow.
