Need opinions on this acrylic cube

[spikehs]

I heard of this guy off of ebay from the people at RC. I was hoping someone here who has some acrylic experiance could chime in.

The tank is 16x16x14 (15.5gallons), Rimless with bent corners. The acylic is 3/8 of an inch. I'm curious if that is thick enough to prevent bowing. From what I've read on acrylic one of the main reasons they get scratch up is because there is bowing when you scrape the tank, leaving two pressure points to cause scratches.

Thanks!
