A:AnswerYes, this case will fit a standard size ATX motherboard AND a 3 fan GPU (lengthwise).
The fans included are rear and top exhaust which in my opinion is fine to start with.
I replaced the exhaust fans and moved the fans it came with to the front for intake. You wouldn't be able to see the front-mounted fan LEDs anyway so I didn't bother with those.
This is a picture of my build with an Asus Z590 Prime and an Nvidia 650Ti. I've replaced the 650Ti with a 3070 triple fan and it fits fine.
A:AnswerIt should be able to, as a standard ATX board fits, and is a little bigger than the one you asked about. The only potential issue is that the HP board you’re asking about isn’t a standard size (it’s somewhere between ATX & mini-ATX) so the mounting locations may not be in the right positions for the case. Conversely, the screw mounts might be fine, but the back panel might not be flush with the case due to the size difference.
Recommendation: find if someone else has installed that particular mobo in any standard ATX case, and if it worked for them, it should work for you with this case.
A:AnswerThe B450 tomahawk max is an ATX sized board. The NZXT - H510 Compact ATX Mid-Tower Case fits ATX, micro ATX and mini ITX motherboards. No room at all for anything larger. You'll be fine with this case.
A:AnswerI have not had any issues with this case, it is likely that the header is wired incorrectly or plugged into the board incorrectly. Check your Motherboards manual for the proper wiring configuration and also trace the wires to ensure they are correctly connected to the Power button, sound like you may be connected to the Reset Pins.
A:AnswerThe case comes with two fans (120mm). It would be enough to enough to run a pc. Both would function as exhaust fans (rear and top). Front panel area can accommodate additional 2 fans for traditional setup or radiator cooler if you are using liquid cooling.
A:AnswerYou could if you don’t want to use the Desktop Hard drives at the bottom. It gets a bit crowded if you are pushing more power cables to drive graphics card etc.
