As anyone who has ever built a PC from scratch can tell you, there's an adage about how "the PC isn't done until the case has drawn blood" ... it's a maxim I learned to accept in the many years I was building PCs for myself or work from spare parts. Without fail, at some point in the equation, I'd slice a finger open and bleed all over the case.
Apparently, there's a similar rule for colocation facilities.
I was in our new cage, racking some PDUs in preparation for the first server installs next week. I'd been uncomfortable, but that was understandable. Crawling around on hands and knees on colo tile (the kind with all the holes for air venting) can be uncomfortable, even painful, so I paid it no mind.
Until I saw a big 3" x 2" smear of bright red blood on the floor. I touched it, it was fresh. I looked down at my shin... yup, nice thin 1" slice from .. well, something on the floor, who knows what.
Like I've always done with PC-case-bloodletting, I let it dry in place. It's a testament to my (literal) blood, sweat and tears from the installation.
I haven't bled on a case for a while now. It seems that even if you buy a cheap case you don't get some stamped metal monster with razor sharp edges. I used to all the time, especially on those bastard sharp blanking panels that are for unused pci slots.
It's been at least a couple years since I've sliced anything with a computer case.. but I still have a scar on one hand from a particularly nasty 486.. (obviously, old scar).
The only nastiness I've experienced with computer cases was with a Compaq Evo...flipped the lid up and had a hard time getting it back down again, so I pushed in on the lid supports (spring loaded it seems) and the case scissored down on my finger.
Most enjoyable.
