Yes. 4U = 1.75" x 4 = 7 inches

4U chassis will accept full height cards, and those vid cards with big
heat pipe coolers. 4U chassis are the cheapest RM units by bar. A 4U
would best fit your needs and cost target. Here's a good one for the $$

Note the cheapest RM cases, WITHOUT PSUs, are the same price as a
mid/high end mini towers w/PSU.

That case above has excellent cooling. However, if your audio rack has
a back panel you cannot use an RM case, as the hot exhaust air would get
trapped inside the cabinet and overheat the PC.

This will not work. The audio rack must have an open front and open
back. If it has a back panel, simply remove it. If you'd rather not
remove it permanently, simply remove it, cut out a rectangle the size of
the RM chassis with a Rotozip, Fein multitool, jigsaw, etc, so the
exhaust air can escape. If the panel is cheap Masonite (pressed board)
you can cut it with a utility knife. If none of this is possible, don't
buy a rackmount case.
