I just bought my dream case after 20 years of BYOPC for myself and companies I have worked for (I am a Programmer and IT Pro) the Cooler Master Sniper BE. This case is huge I had my Ohm meter laying in it while taking ground readings. The front panel is great with its fan speed adjustment and light on/off switch. Its not the prettiest, but it's about as functional as you can get. Even full towers don't offer much more if more room (depending on the case of course). But wait why does it reboot when I touch the top panel at times. I got one of those bad, poor quality Cooler Master cases , not!
I Googled and read all the forums and even the Cooler Master forum, same problems, same tests, same results as me; you can't find an answer it seems. If you search Antec they have the same problems! For some reason some cases don't however. But I have to say some members here did nail it, but it's being over looked a lot as not the right answer because it's too simple. It is me, I am holding a charge. Notice this problem is getting big right around the start of winter? I live in Michigan and yep house is dry because of the cold air and the furnace. We do have a humidifier on the furnace but it went bad some years ago. I bought one of those larger type portable humidifiers. Not for this problem, but for my wife at Christmas. She was saying it's too dry, her skin is drying, her hair gets pulled to metal objects when she walks by them LOL... it's designed for 700 square feet, but its in the bedroom and I guess not big enough to get to where my PC is located (need to fix the old Lobe furnace humidifier).
I disconnected everything from the front panel of the Sniper case but the power switch and stopped the reboots from the panel, but it would now reboot if I touched any metal part of the case! I studied static electricity a bit yesterday. It seems a case made of plastic will hold more of a charge than metal! The material the case is made of is not a big factor. The Cooler Master cases are well grounded. The front panel is isolated but is grounded from the USB and other headers. My wall outlet is grounded. What is happening is the power surge from us is going right through the case to the PSU via direct ground or motherboard and out the ground. The power supplies are rebooting the cases. For me it's a half way boot, I have to do a reset to get it back.
There really is no technical problems with the front panel its just when you touch it the surge goes down whatever path it finds which for the Sniper case is the USB and other ports, into the motherboard grounds into the PSU and it reacts. It could be going through the MB and its reacting. I know my MB has those reset and power buttons right on the board, perhaps a bleed to them? But IMHO its the PSU and grounds in the case and MB. But if anyone knows I am not an electrician but a programmer; so chime in. I am not 100% sure my outlets are grounded. Technically they are. I pulled off the cover and the copper wire is hooked up to the outlet. However I can't test them until I get my little tester Monday from work and make sure. My gut feeling is the PSU should let the spike go straight to ground and never through any circuit and reset.
How do I know for sure my problem is found? My PC speakers have a separate amp (Genius SW-V2.1 1250) and I can hear a pop through the speakers when I touch its back panel after dragging my feet around the room; then when I touch the PC no reboots ever (so far)! Hurray an audible and visual (spark sometimes) confirmation it's me! Its not really a design flaw, other makers have the problem, Cooler Master does make an awesome case (and others ) and my case is fine.
I just went and got a cup of coffee walking on the carpet with my slippers came back sat down touched the back of my amp and I could hear the pop, discharge. Touched the case no reboots or anything.
Now I know this may not apply to all but I hope it helps a lot of folks. The cure is to discharge yourself before touching your case in this case
