maybe 4U will do. that depends on your rails and bias.

How much for the 5u cases ...?

IMHO, these cases have too short fins.

Better to start with apropriate heatsinks and build your own case around.

HiFi200 cases:
5U/400mm w/10mm faceplate is EUR210 (4 200x40x210mm heatsinks)
5U/500mm w/10mm faceplate is EUR260 (4 250x40x210mm heatsinks)

They have volume discounts 2 = 6%, 3=10% .. so for 2 it's EUR244.40 plus shipping. Shipping won't be cheap, so get a quote before you order. If shipping to the US, expect a call from FedEx explaining the material of "screws" are made from...

I would ask for blank rear-covers as they sometimes have cutouts for power sockets and you might prefer a different location. You can also ask for blank top/bottom covers, full vented top/bottom covers for no additional charge.

Not really a fan of the feet they offer, they have a rubber insert with a hard plastic exterior shell that falls off. I've picked up some Peavey feet that seem to do the trick better than what HiFi offers.

Bracing with for the bottom cover is lacking. If you notice in the picture the top screws are only on the sides, the bottom is the same, but there should be something in the front and back as well if you plan to mount feet and a heavy transformer to it. Easy to address though, but something I would recommend asking HiFi for those about to order the case.

have you tryed?
i have. so i know they perform.
with 100W dissepation pr ch. the sinks was about 20C above ambient on a 5U 500mm.
the fins are not smoth. so the aria is same as at least 60mm smoth fins.

At those prices + shipping to the US, I would think it better to build your own case .. DIY ... look at that...

that depends. heatsinks are expensive and heavy and expensive to shipp.
also, 10mm frontplate and oxidised is not cheep. i bet a simmilar DIY chassis will cost just as much. most have to get sinks shipped half way around the world.
