I've started working on a design (not anywhere near finished) and was having trouble figuring out the part at the back of the case for the PCI slots. Then I started wondering if there are parts for sale which could help, as in there would just have to be a large cutout at the back in which the part could be mounted. I found this one.

Unfortunately the shipping costs are so high that it would work out to 50 dollars just for this relatively small part of the case. I've been trying to find something similar for sale in the UK, but so far haven't had any luck. Would anyone have an idea about this?
