anyone out there have a shelf, or mining rig that they got that seems a bit unsteady because of lack of contact point?
all of the square tubing rigs I have seen as well as most of the angle aluminum rigs I have seen all seem to suffer from this, and though a single case should not be a problem, when you start stacking them up with the weight of all the hardware on the above cases gaining leverage over the bottom case, I am sure it will not take much to cause it all to topple over causing a lot of damage to your mining hardware investments!
This is something that can be sorted incredibly easy and I am offering packages of reinforcement units to solve this if you feel this is important to you. also note that the stacking rigs that firmly connect, this should be able to be deployed on the bottom rig and maybe one or two in the middle of your stack of 6 or more lol, stabilizing the whole stack substantially even if you have box fans hanging off the side pulling on them a bit. though mounting them on all frames will give maximum stability

for a guideline I have the ones shown on this corner that measure an inch between holes and enough room in the cut out area to allow for 1 inch angle comfortably, with the edge from the sides of the angle being identical on both sides
also any rolling on the edges to avoid sharp edges is experimental and can be done as plain flat fold over to avoid the roll from intruding into your case inside volume of area, ( I noticed this with my very first design where the powersupply is mounted in the corner to the angle) (the one pictured at the end of this post has holes that work for 4-40 screws but the size of the screw hole is customizable up to one quarter inch sized screws and bolts if you want. also thickness is about .020 on the pictured one, but thicker metal can be used, just expect it to drive up the cost of shipping for a lot of them in one pack a bit lol.
8 pack of these would be 15 dollars made from aluminum sheet, and $12.50 for steel sheet. this is enough to mount say on the top bars on both sides all the way around to allow for there to be one that is always being stretched and one that is being buckled on no matter what direction your case is being pushed on avoiding any movement and giving maximum security, and if you insist on 20 of them (total of one for every corner around sides top and bottom and one for each corner on the top of the case) I can do custom cut out holes for thing to poke through like USB ports and what not. just let me know. On tube frames you will have to either drill all the way through the case to get a screw all the way through and a nut on the back side of it if you can not do threading on the tubes and this is of course much easier on angle.
if you want something with custom hole placement and sizing and I am sure I can work something out for you.

(I can also coat them with epoxy enable spray before shipping for a small extra charge if you want.
just let me know what you are seeking package wise and I can get you a quote on custom units, or custom quantities and see what we can do to cut down on shipping costs. I can even do double box bends so you can mount to the inside faces of those tube cases to avoid any thing even as thin as a screw head or the bracket from sticking out the sides of the case, again just let me know.
on shipping charges I can pack quite a few of these into a one pound cost box to ship them to you. so holding off and ordering all of them at once will save quite a bit since priority mail for a one pound or under box is only about 5.50 to most of the US states.

for those not comfortable with any of the above, I will be making cases shortly that use 1/8th thick aluminum angle and will be possibly offering some with titanium angle too, and will be including these and all the custom brackets to mount hard drives and optical drives as well as two power supplies, 6 GPUs, larger case fans on back and side if desired as the mounts will have several contact points, for nearly all parts even the rails to set and clamp down the GPUs to change the height they sit over the motherboard, and motherboard for around 175 and future upgrades will be things like quick change contact points to stretch air filter covers over them so they still allow maximum air flow but catch most of the dust, cutting down on your maintenance of you systems, and you can just toss the filter into the washing machine to clean them periodically, possibly even with custom patterns printed on the filters to tidy the look of your mining farm up a bit
