As a long time Lian Li customer / user and a fan of all aluminum cases, this seems like a simplified and cheaper "Lian Li PC-V700".
They changed the general outter shape of the V700 and removed the awesome fancy features like 'SATA back-plane' & 'Tool-less PCI card holder'.
That's fine if that is the intention, but the MSRP better be cheaper than the V700
Things to fix:
1) The hole right above the motherboard has no rubber padding; why is that? That seems very inconsistent and should be fixed by adding rubber padding.
2) As for the easy Optical Drive bracket, that's a needless expense IMO and should be removed in favor of the traditional screw / hole pattern that matches the other side.
3) Since this seems like a simple case with basic needs, you should also release a case SKU without the plastic window panel, not everybody likes the plastic window panels, I personally prefer the all aluminum side panels.
4) The rear handle to pull the case panels back for opening is too low, part of the power plug is covering it, the handle needs to be moved to near the center of the case where there is no obstructions to reaching it.
5) There should be some basic casing color options, Black, White, Silver, Red, Blue with contrasting interior panel colorings to make things stand out.
