Yes, if I decide to build an S402 I'll plan on including vents on the now solid panel so 120mm radiators can be used.
While I'm on the subject, I've prayerfully decided that after I sell out of S401s, I'm going to take some time off from the case business. My goal would be to try and have something new this fall/winter like I did with the S401 but I'm definitely not going to have as many made. I'm getting very burnt out - it's nearly midnight and I still have orders to pack for shipping out tomorrow. I also have e-mails to answer and pictures to post but I'm too tired to do so now.
If that weren't enough, my work has been extremely stressful lately. Enough so that I lost it with my boss last week and in the 12+ years I've worked there, I've always been in better control of my emotions. Two kids, being active in my local church, and running this business on the side has taken its toll. I do intend on making another design available but as the S700 is not viable, it will probably be the S402 or S500 depending on my mood. I'm nearly sold out of S401s (have about 3 left that are packed with 10 more waiting on more parts to arrive before they are finished). Once those are gone, I'm probably going to be a little more scarce on this forum until I can get other things addressed in my life that have taken a backseat these past several months. Regardless, I'll still have the custom panels to sell, as well as some of the accessories (fans, disk stackers, spacers, etc.). Some of the accessories I don't intend on restocking though will be the Demciflex filters and removable handles as I lose money on each one of these I sell.
Sorry to hear about the struggles man - I think we've all been there and life can really suck sometimes.
Please absolutely take care yourself and your job and your life way above any of this stuff.
Cheers!
