@xan_user, Thanks. The 2014 cases are basically the same size, but not exactly the same:
L1 (2013) dimensions: 220x93x222 mm
L1 (2014) dimensions: 220x94x220 mm
I haven't thought about a modular case in the past, but it's not something I'm considering doing. A NAS case... perhaps.
I'm not aware of anyone using a GTX 640, or of any GTX 640's that actually follow the low profile specification (in terms of cooler height). The Sapphire HD 7750 Low Profile seems to be the go to card for this case for those looking to do some gaming.
@porkchop, Thank you, luckily they stand behind their work, but still a challenge and time sink. I did try a new powder coater this time because I wasn't totally happy with the last one. They did an excellent job with the coating, but they failed to keep the parts properly protected from touching each other. Really sad, considering it was so close to being a success!
@thierry., Thank you, glad you like the bigger openings! I appreciate your suggestion. It's a good idea, and I'll try to implement it at some point. Just need to find/make the time to do it!
