Yeh its very odd indeed.
But I would say the service far out ways the chance of a damaged case (in which you can just get a re-placement from the seller or something) or if it's a side panel/fan controller/the top panel on the midi just contact fractal and boom, they will send you w/e you need for free!.
Bizarre....
I had a arc midi for a few days which I planned to transplant my current rig into.
The top panel part of it was warped (the mesh, very common problem from what I read with the midi), it wasn't distracting but I knew it was there and if I looked at it, I would get annoyed....
I emailed fractal, told them about the issue and within about 20min I had a reply asking for my delivery address to send a new top to me for free....
It was just past midnight, was going to sit down in the morning and transplant my computer into the midi and put the new top on when it arrives.
Looking around google before I go to bed and came across a video titled "Arc Midi R2 High Performance Case Walkthrough" I was like midi R2? whats this? click...
I was like....You have got to be kidding me fractal
So I RMA'd my midi as faulty and got a full refund as the R2 fixes all the issues the midi had
I can vaguely remember that OCUK took fractal of the website because they where getting a buttload of returns for "faulty" fractal cases and they didn't want to put up with it anymore...or something
Anyway, really sad they arn't on OCUK anymore, have to order from other places that don't have the same reputation/longer delivery times/crappier returns....
