I did something similar. Ikea tabletops for the desk surface and back, two legs I found on Amazon to support the very ends, and a bunch of brackets from the local hardware store.
Biggest bonus was being able to set the height of the desktop to fit my short legs. Having a desk top at 26" looks somewhat comical, but now I can sit with my feet flat on the floor, knees at right angles, thighs resting on the seat, elbows and forearms resting on the armrest and hands resting on the desktop/peripherals. Nothing bent at an odd angle and no pressure points. The difference has been way more than expected.
Second best part is having a big L shaped desk with nothing to bang my knees on from one end to the other.
My initial reason for putting my desk together was also height. Too-tall desks were giving me literally debilitating neck and back problems; my neck was so fucked up it caused constant dizziness which took months of physical therapy and daily exercises to only partially alleviate. With a lower desk and a petite-sized office chair, I can sit ergonomically and feel 100%. No dizziness and I don’t even have to do the exercises anymore! Literally life-changing.
