In Photoshop™...
But I was curious if I'd need to adjust the height in photoshop, or if I could maintain the proportions, so I did not allow myself to use any control that didn't keep proportions, and it seems to fit... At least virtually.
Why didn't I use a tape measure you ask? Because the other set is stored at another house, and that would be a hassle.

What if I gave the cheap cabinet to a needy VK'er who has the same model with a trashed cabinet? Then no TVs are lost.
True, I hate hot-rods. But this isn't a '42 Desoto with a stupid camaro subframe and small block Chevy. This is more like using a 228 cubic-inch 6 cyl, from 1941, vs. the proper 236 ci. 6.
My last conversion still gets compliments:
(I didn't trash the Porthole! It was done before I bought it!) But I am decent with a sawzall...
Either way, you needn't worry for a while. For now I've got way too many home destruct... err, "improvement" projects going on to find time for something fun like a TV!
For now nothing will be going inside it but little RubberMaid
® tubs full of DVDs and CDs.
