Thread: Anyone else?

Not long for an ALM 52hp 6U case and tonight after finally getting a few modules decided to set it up. All was working ok until I tried to screw down the top row of modules, they don’t fit! So I relocated them to the bottom row and they’re a perfect fit, back to the top row with 2 x new modules and it’s a no go again. It looks like the top row is 2mm undersize.
Obviously I’ll give the retailer a call in the morning but I just wondered if this is a common problem or if there’s an easy work around?
