As much as I want this case, it's a turnoff for me to have the power switch located at the bottom of the case.

Thanks for posting this OP Smilie .. but yes like Frank Nitty said it's a bit of a head scratcher why the power button and usb ports are at the bottom of the case? Could be because it looks more stylish Smilie ... but if you're relying on something that involves a usb cord (some of us old school people - too cheap to upgrade when current gear works fine basically Stick Out Tongue .. still have say for example wired xbox usb controllers ) you may not have the extra cord length because the usb slot is on the bottom.. honestly given it's advertisement as "modular" I'm surprised they didn't design it in such a way that the usb part can't be repositioned up at the top (I know this has been the case - no pun intended Smilie - with other PC cases)... unless it is possible and I'm just being ignorant Smilie .. for people without those old-school usb needs I can see how it would be a good case Smilie

If you have a setup where the pc is raised up, like on a table, its actually better that panel is on the bottom and not on top. Its very easy to remove the panel and front mesh screen for cleaning/dusting.

I have this in black. Case is great to build inside. If it is raised, it's a great case.

Too bad it's hard to build a PC now with RAM and storage prices.

Keep looking for Ram and NVME at Amazon and Walmart. I keep seeing and snatching both when they mysteriosly come back into stock (locally at WM) and a reasonable price. Crucial is the brand I see most. Sometimes WD. Some walmarts do sell Ram (along with cpu's and video cards) and most all sell Storage.

My suspicion is that this is all a power play to cannobilze these items so our rivals cant - giving us the advantage in AI, (esp Military advantage). But the stock slowly seeps out for brief moments.

I dislike the bulk of the 5000D, but it does have infinitely better button/port placement.

And the case is not that hard to clean; you just need an air duster.
