Eh, I just don't like it. Plus my case is older and has more slots/holes for screws and it's not a clean flat surface like in your case. All I'm saying is, they have bays for everything else, and ssds are so small and you need only 1, maybe 2 bays absolutely tops so it seems odd that all the years ssd has been around that no one makes a little locking slot for them. Just seems silly. What do you like better about other specific cases? I don't think you answered on the last page and they all seem pretty damn similar with very minor if any differences. I've never owned antec so I have no personal attachment to them.
Apologies on not getting back to you on specifics. If you don't like the look of it, you can even mount the SSD behind your motherboard tray. This keeps it entirely out of view.
If we're just talking about the two big boys, 690II and Arc Midi, the following:
1) Modular drive bays. Having a big hunk of metal entirely block the front intake is bad design, despite being standard for a number of years.
2) Eleven Hundred is designed around negative pressure for cooling. This means worse temps and very dirty case. There's not a single intake fan. You'll need to buy an additional 2 120mm fans to get it only slightly negative. Not to mention the included fans aren't great.
3) I really dislike windows that have fan cutouts on them. Totally subjective though.
4) No 240mm radiator support. H100 is really popular, and open loop watercooling kits are becoming more and more popular. Big oversight here.
5) Build quality. When you go to big LANs often, you see Antec cases that are just totally falling apart. If you leave it in one spot and never really touch it outside of the random upgrade, this isn't a huge concern. The Eleven Hundred has that same cheap feel.
6) In comparison, bad dust filters.
7) When I did a build in it (friend who just really really wanted an Antec case - brand recognition), the front panel wires aren't even long enough to route properly.
8) No rubber grommets on the top routing holes above the motherboard.
I'm probably too picky, but #1, #2, and #5 would be enough to dissuade me from buying it or recommending it. There's just no reason to buy one when there are so many other great choices out there for the same price or less.
Random input, I'm so glad I 'downgraded' to the 600T White, what an awesome case. Love the design, the color combination, how the top fans for the H100 are hidden away, the temps and the easy fan control setup. Best case I've had to date.
Only negative is the plexiglass window, scratches up SUPER easy. I had it lying on the floor whilst building back then and it got super scratched, tried to wipe it off and I scratched it even further. Looks like a cheese grader now. Luckily I was planning to use the mesh.
Glad it's working out for you! Not sure if I shared my protips for the case or not, but:
1) If you clip off the plastic on the top and front pop out panels, it greatly reduces noise.
2) 200mm fan on the front can be replaced by the Spectre Pro 200mm. The stock fan is pretty loud and doesn't push quite enough air. I have a few extra from my 600T if you need any.
3) You can move the front drive tray to right next to the PSU, which gets it almost entirely out of the way of the front intake, helping to cool down your videocards.
