Re: Multi-CPU general motherboard design

I'm pretty confident that no consumer grade motherboard does this.
As for DIY: Have you made (m)any motherboards before? Takes some pretty advanced tools and knowledge. Getting help from AMD's engineers should also help.

Re: Question about tempered glass

I'd be surprised if all tempered glass is the same, but I see no reason why a panel intended for a railing shouldn't work as a floor cover, provided the floor underneath isn't too soft.

Re: Fan round up - Best 140mm and 120mm

Would a good exhaust fan have different characteristics from an intake fan? Yes, but exactly what characteristics you want from the exhaust fan depends on the total setup. * If the exhaust fan is to provide all airflow, with no intake fans present, then it should be (relatively) high flow. * If you...

Re: Should airflow be prioritized with cases?

IMO you should not buy a new PSU "just because". The only reason I can think of for you to buy a new PSU is that you also buy a new computer case where a CPX PSU won't fit. If you buy a new PSU anyway, then don't go for that severely overkill! Just get one rated for 500-600W. That should save you so...

Re: am i asking for trouble

Provided that the PSU puts out "dirty" power or voltages severely out of specs then it can harm the other components.
The probability that the CP-850 will do that is as good as zero!

Re: what difference does 8 gig ram vs 16 vs 24

8 GB can be limiting for example when having several browser tabs open and/or multitasking.
If you're editing video or high resolution RAW pictures more RAM is also desired.
16 GB is usually sufficient.

You don't need much power for your current components. A 400W PSU should be plenty for that.

Half of the (tape) width on the aluminium plate and then angled up on the side of the fans. Even if it isn't a perfect seal it should provide enough flow resistance to basically eliminate the leakage.
