I will admit to being fascinated by Antec’s latest case. It’s more of a skeleton than an enclosure, providing mounting points for all of a computer’s components to screw into, fans, and nothing else. I especially like how up to four additional hard drives (in addition to the two it fits “internally”) can be clipped onto the outside. Despite the case’s goofy novelty, this really is something I could get into. I tinker with my computers a lot, often running them with the sides off in between swapping out hardware, so this wouldn’t be that much of a stretch. Heck, I’ve run computers with IDE ribbon cables connected to “external” hard drives sitting on top of the case; the skeleton case’s mounting option would’ve been really nice. And above all, I just like the idea of being able to see the components in my computer (which I paid quite a bit of money for) at all times.
But I’m also a bit of a realist. There is a good reason that all other consumer-level computer cases are, well, cases: it makes sense to put your computer’s delicate vitals inside of an enclosure. The case helps keep dust out. It also keeps objects from falling onto the computer’s components. Drop a sizable object onto a normal computer case and the worse that will likely happen is a large dent in the case. But even dropping a coin into the internals of an exposed skeleton case could short out some contact points on the motherboard, or get caught in a fast-spinning fan and turn it into slying shrapnel. Dropping anything larger could easily cause substantial damage to delicate internal components that a 1mm thick steel case wouldn’t blink at. And let’s not forget the problem of spilling food or drink. Spill something on top of a normal case and odds are good you can quickly wipe it up before it seeps in (and the case itself will deflect most of it). Spill something into a skeleton case, and you’re almost guaranteed some kind of catastrophic failure.
But even if you’re never clumsy, and you set up your skeleton case in such a way that there is zero probability of anything ever falling on/into it, there is another less obvious problem lurking: radio frequency interference (RFI). One of the reasons computers and most other electronics are sold enclosed in metal cages is to prevent RFI (even when the exterior is plastic, there will be an internal metallic Farraday cage enclosing the electronic components). Electronics are sold this way because of a sensible regulatory requirement by the FCC to prohibit your household electronic devices from interfering with other devices. Since the skeleton case doesn’t ship with any electronics in it, it can get past the FCC, but no computer retailer would be able to sell a pre-built computer inside a skeleton case. Computers, having all sorts of components in them running at various clock speeds, produce quite a number of radio waves of various frequencies.
The RFI produced by a computer can potentially interfere with nearby electronic devices. It might cause a hum on a speaker system, for instance, or produce static on a radio (ham radio operators on HF frequencies especially should stay far clear of skeleton cases). Depending on how severe the RFI produced by the computer is, and on which wavelengths, it could interfere with wireless mouses and keyboards, or even a monitor. There’s no way to be sure, really — the specifics of RFI are really finicky, and depend as much on the characteristics of the receiving device as of the computer in the skeleton case. The interference also works both ways, so your computer could suffer some rather catastrophic crashes if parts of its circuitry happen to be resonant with a nearby source of radio waves. Considering that I pick up low power AM radio through my bass guitar’s unshielded instrument cable when I turn the gain all the way up, it’s not far-fetched to imagine interference affecting an unshielded computer as well.
But I’m just making educated guesses. What we really need is cold hard data on how much RFI an unshielded computer puts out, and what sources of radio waves one might expect to interfere with the computer. Unfortunately, ExtremeTech didn’t examine this angle at all in their review, and my lack of a test bed (let alone the willingness to pony up $190 for the case) precludes me from finding out myself. So I really wish someone would do the requisite experimentation, because the skeleton case concept could be completely DOA for reasons less obvious than “you might drop stuff into it”.
