A friend built an X58 system years ago in a Thermaltake Level-10 case. He upgraded here and there, including more RAM, newer and better GPU, more HDD's etc. Sadly, the old case started to show its age, with feet that broke off, USB ports that worked only sometimes, and its big. He got married and having this big angular relic of youth might have influenced his decision too. So he ordered an all white, non-windowed Fractal R5 and had me move stuff over.
As far as I can tell, my friend picked the R5 due to its more svelte, sophisticated looks, plus it was one of only a few mid-tower cases that offered room for all of his 3.5" drives, plus comes with room for three more. He really likes 3.5" drives, you see. He also really doesn't like PC cases with windows, and when it came time to order, the non-windowed version was actually more expensive then the windowed version, but he stuck to his guns and got the windowless version anyway.
Building in the Fractal R5 was as easy as they say. The center standoff post was a nice help, and getting the other standoffs in place in their marked locations was quick and easy with the included plastic standoff bit thingy. Just keep in mind the fact that the said standoff bit thingy is made of relatively soft plastic, tough enough to get the job done for one install, maybe two if you're careful, but not much beyond that. This case would also be better with a modular PSU as there is no shroud to hide the leftover cables otherwise. My friend is still using his older non-modular, and I'm not super impressed having to leave a big wad of cables visible. I suppose it is what it is with having a traditional multi-3.5" HDD rack at the front though.
A note about the HDD cages. It comes with two, stacked vertically. A large 5-bay, and a slightly smaller 3-bay. After pulling the cages and separating them, I installed the 5-bay cage alone on the floor of the case. While this works well enough and is what my friend wanted, the bottom HDD cannot be removed without removing the entire cage itself, so I installed the boot drive there figuring that there would be more need to be able to easily pull the extra drives, so it would be better to leave those accessible.
The case comes with two rather pretty Fractal 3-pin 140mm fans, one in the front top, and one in the exhaust position. I grabbed another 140mm fan of unknown progeny from my friends case and installed it in the lower front position. The case comes with a built in, SATA powered 3-fan controller with female fan pin connectors on cables, so I just hooked them up that way, giving my friend access to the three speed controller inside the front door. Unfortunately, I can't tell you much about the noise level of the included fans, as my friend is still using the stock Intel cooler with his 130W X58 i7-950. That thing sounds like a leaf blower, and drowns out just about everything else.
Anyways, here she is. A white, windowless Fractal R5 with a classic X58 system in it.
A note on the parts list: some of the items listed are approximate. I couldn't find all of these older parts on PCpartpicker's listing system, and so I selected equivalent parts where necessary. My friend's X58 motherboard also doesn't have an internal USB 3.0 header, so I had to leave that unhooked.
