Nothing but those razor thin 'paper cuts' you get from working on the inside of old style bare sheet metal cases everyone seems to get.

How exactly are you supposed to get circuit boards in place without cutting your fingers? There seems to be no reasonable way of doing so that does not risk harming the board in the process.

After hearing this I now make sure to keep the U shaped shell well out of my way when working on my old AT cases...that sounds awful.

When the stuck connector finally gave my hand jerked brutally against an edge of the computer case. The back of my hand hit the sharp metal edge which resulted in tremendous pain and a burst blood vessel. I initially feared I had broken a small bone in my hand considering the brutal shock but It healed pretty well despite the initial pain and hematoma.
..glad to hear it healed ok...once I did a similar thing in my old NEC computer case trying to pry out a molex, but instead of catching a sharp edge and cutting my hand, I only banged it pretty hard and bruised it pretty bad on a blunt edge (thankfully). Now I try to use a set of pliers and make sure there is nothing behing that can hurt my hand.

How do you mean? Slow and steady has always worked for me, but it does depend on the enclosure; I like big towers for a reason.

Great, another thing to fear... 🤣
In all honesty though, usually those u-shape cases get to hold my toolbox though... 😀

DIMMs have been the worst in recent experience, they have a sharp edge and seem to require considerable finger pressure to move into position. PCI cards and the like can occasionally be rough as well.

Most DIMMs that I've encountered in recent years have spreaders that mostly allay that. Putting them in at an "angle" can be easier as well. Rubberized handles on pliers (or similar) can also be used to apply some pressure in lieu of your fingers, if that helps. On PCI cards (or other add-in cards) I've never really noticed "sharp edges" as a problem - some newer add-in cards also have spreaders/covers (the nVidia Quadro cards are a really good example of this) which can help (but make sure you aren't applying all of the pressure to a heatsink or shroud, as that can cause damage). The ones that don't, I usually inspect to make sure I'm not grabbing on a "break off" point (where the PCBs were separated in manufacturing), because those can sometimes be pretty ragged. One thing I have noticed with a lot of add-in cards is the I/O shield usually isn't "straight" - you usually have to help that seat right (if the card is refusing to insert or sit flush it's usually the I/O shield, not the shoe), so putting some pressure on the I/O shield from behind the case can sometimes help coax the card in. If that fails, I usually pull the card back out, get the pliers out, and bend it into shape. 😈
Apart from standars cuts on cases while sitting cards etc that is already heavily mentioned, I can only remember of one other nightmare (I was working as a last-cog technician back then) : Early dram memory modules, still coexisiting with simms, that were ment to to be fitted on first socket 7 m/b's... #$@$%@%&*!
I'm still not sure if this was happening because of m/b slots or because of the dram chips themselves, but back in the very beginning of dram, placing such a module on the m/b required a lot of force (and in some cases blood). Most probably specs weren't as precisely set as now and sizes might had slight defferences. There are stories of boards going into production theoretically supporting memory chips not yet released, so there might be some truth in them...
In any case, regularly working as a tech adding memory with closed eyes and trying for half an hour to place a mem chip into its position without breaking it is surely something worth mentioning! Especially when your finger was the looser 😀
Not much at all.
Only one time i don`t know what was in my head, but i opened a PSU and while it was in my hand i did turn it on and i get zapped, don`t know why i did this, maybe to get the feel of electricity....
But as i read what others have done, at least no one did cut himself and bleed to death 😵 😵 😵 😒 😒 ...

A few years ago I was taking apart an old hard drive. On the top cover there was a sticker that was holding a circular metal cover disc in place. I pressed it out with my thumb. When it popped out I cut my thumb very deep on the sharp edge of the hole that that circular cover was over.
Nerve damage.. oh yeah! Part of my thumb is still kinda numb.
Until you have nerve damage from working on computer stuff, you are just a noob. 🤣

Noone here has reported injury that resulted into their deaths yet. Maybe tomorrow 😜
Here the injuries are usually getting cut or having strain problems in my arms or shoulders from gaming too much.
I've also gotten 'powered up' by electricity but that didn't harm me in any way. I think? What was I doing here again? What is a vogon? 😕
My nails usually get the worst of it.

I got a deep gash on my hand when a screwdriver slipped as I was removing a metal plate from a 5 1/4" drive bay. The case was one of those cheap ass things everyone bought in the early 00's and had sharp corners everywhere. It only required 3 stitches to fix the hand, but I was a bit shocked when I realized I could see all the layers inside my hand (skin, fat, muscle) before the blood gushed out. 😵

If anyone here reports on their own death, I'm leaving. 😲
Now for some blitting from the back buffer.
My only problem lately is being tired after playing world of tanks for up to three hours a day for weeks at a time (grinding during events) 😒
I am looking forward to a vacation of sorts so that will be fun.

How about McAssey installed on every freaking Dell ever sold? I swear the amount of times Iv worked on a nice XPS or Optiplex and heard "I hate Dells, every one Iv owned has been slow!" Followed by "Wow my Dell is so fast what did you do?" Well gee got rid of the Malware that your quote: "Anti-Virus" missed, then uninstalled McAffee and enables MSE.

When I was a kid we were visiting relatives and I got into playing "Decathlon" on their Atari 2600.
To do well in that game, you need to make your guy run as fast as possible. You do that by pressing the joystick left and right as quickly as possible. The recommended method is to place your thumb and index finger on opposite sides of the joystick and "waggle" it.
I got some painful blisters from that game. When my elders noticed, I was basically forbidden to play it anymore.
