I am trying to build a full size computer but I am having trouble finding a case that fits within my space requirements.
It needs to fit in an alcove that is 19" wide, 18" tall, and 12" deep. The board I want to fit in it would max out on memory at no less than 64GB and and have PCI slots for a sound card, SSD, and 1-2 high end Graphics cards.
I have found a couple cases that fit in that space but they leave a lot of unutilized width wise and the motherboards that fit them are severely limited in memory and PCI slots.

So I was wondering if anyone knew of a specific case that fits those requirements or know where I could get one made?
