Thanks again for helping out.
I couldn't resist! If my posting this offends members, I'll take it down shortly.
Just wanted to show y'all what I was up to with my data/mining closet:
As you can see, there is still some work to do. Still waiting on several 240V/30AMP outlets to get here from California [Ordered from Amazon]. This means I'm pulling out 5 of the 7 12/2 wiring to replace with 10 AWG for the new 240V/30AMP outlets.
You see six (6) different colors of SF Cable, 6ft IEC C14 to C13 Power Extension Cord 10Amp 250V 18/3 AWG SJT.
They will be used to plug into two (2) Tripp Lite PDUMV30HV PDU
Metered 208V / 240V 30A 6 C19 24; C13 L6-30P Vertical 0URM's. One of them is to the right [Out of the box] and one is on the left [Still in the box].
The bottom shelf and the shelf above it will have to me removed temporarily to install the Tripp Lite PDU's on the back wall. The shelves will be repositioned [When re-installed] to allow enough space between the shelves to be able to turn S4's onto their sides to help me place more S4's in this closet than previously intended [25 S4's instead of 20].
[If y'all think they should not be positioned onto their sides, please let me know and why?]There is a 14 inch Can Fan Max with 1820 Cubic Feet per Minute (CFM) of suction for this 122 cubic feet closet. You also see a 16 inch return near the ceiling in the back where the 14 inch Can Fan Max is connected feeding into the garage. [Working on duct work to feed the hot air to the outside from the garage.] This is a youtube video on the 14 inch Can Fan Max:

You will also notice a 16" x 25" filtered grill in the closet door in the second picture. This allows the 14 inch Can Fan Max to pull in TONS of cool air from the recreation room downstairs.
A window is open just to the right of that closet door in the recreation room to allow the fan in the closet to suck cool air into the closet. Enough air is sucked into this closet that it will blow your shirt over your head if you were standing in the closet without your shirt tucked into your pants.
Hollow square metal rods will replace the wood bracing I have underneath the shelves I have soon. All wiring will be neater as well once the PDU's are installed and shelves are re-installed after proper spacing.
A little bit of history with more photos [even of what is going on behind the closet wall in the garage] of what I've been doing through trial and error can be found here:
https://bitcointalk.org/index.php?topic=766998.40I'm remodeling my recreation room. So, don't mind the base molding that has yet to be nailed on, primed and painted.
re: the metal bracing, I'm just wondering whether you ought to consider fitting a central vertical support pillar on those shelves as well (from top one down to floor)? Also, is there any way that you could duct all that hot exhaust air around the building, instead of just into the garage? It would save on your heating bills in the winter and you could have a by-pass duct straight to the outside air for use in the summer (no need to run the aircon unit then). I appreciate that it's easier said than done and ducts aren't the nicest things to look at in living-rooms (perhaps you have ceiling and wall voids to hide them in), but it seems such a waste of valuable heat.
