Does anyone have any suggestions for a under desk PC mount, I haven't been able to find anything that can fit my case.

I've been looking for around a month now and havent seen anything that can fit my case. Dimensions are 22"h x 10"w x 21"l and its about 50lbs, maybe a little more.
At this point, I'll even take suggestions for some sort of furniture that can elevate the PC or something, as long as my cables wont get pulled on by my desk standing up.
