The CPU-cutout looks small - perhaps an Intel back-bracket's bolts will be covered, or almost, by the motherboard tray. Taking that cut-out an inch wider (towards the case front) would have assured easier clearance.
Also, motherboards with SATA pedestals won't have easy clearance to the bottom SATA connectors because the tray has no direct-in-front-of-pedestral cut-outs. Of course, with the limited HDD space, the target market won't be for folks with more than 2 or 3. I wonder why they bother wasting so much metal in the first place then?
