1) I'm debating between the following RAM. Neither is explicitly listed on the H87-PRO compatability list, but it seems like similar ram from the same brand is listed: Crucial Ballistix Sport 16GB (2x8GB) DDR3 1600 1.35V ($115) or
G.Skill Ares Series 16GB (2x8GB) DDR 1866 1.5v ($127-$12.70=$114)
I also was on a similar dilema, i wanted very low profile memory as im still waiting for Noctua NH-D15, and now a days memory heatsinks are more a marketing and visual thing that a real practical cooling solution, beside the way the current gens of platforms overclocking memory isnt as it used be in terms of gains on OCing. At the beginning i wanted the super raved Samsung 30nm
which is also a very low profile memory, its been value by a lot of ocers as one of the best, but its very expensive now as there is no supply on newegg/amazon only imported directly from japan and they didnt release 8gb modules... only 4gb so went to look for similar memory in terms of height so could have the option into moving into a twin tower cooler down the road, so i found Crucial Ballistix Sport Very Low Profile 32GB Kit (8GBx4) DDR3-1600 1.35V UDIMM 240-Pin Memory Modules BLS4C8G3D1609ES2LX0
, and was on sale when haswell was released at $203, all the other kits were almost like $140 for 16gb, so why not.... gonna gamble with it even if it wasn't on the Asus QV list, and it booted fine on my Asus Maximus VI Gene, XMP was recognized fine and its running at 1.35V, no issues at all.
So here is up to you, its a gamble that paid off for me, but i always recommend to go by QV list, as Asus does test a lot of memory with thier mobos, but again up to you.
2) On the case, I was under the impression that the windowless models will be quieter. It doesn't seem that SPCR has reviewed the R4, but does anyone have any experience if it is really that noticable? I'm wondering if it is worth the ~$25 price difference.
I seen sales of both models, just right now is the windowed version, i linked out of the price was much lower atm. Probably the none window will be quieter, but in my experience as long as you put very quiet components inside the case matter little, not to say doesn't matter at all. SPCR has reviewed a lot of quiet oriented cases, and most get silver awards, and not quiet oriented like Silvestone FT02 and TJ08-E have gotten editors choices, out of their cooling, design, efficiency etc, i have built on TJ08-E a very quiet build and been happy even if this case wasn't made on quiet computing. I'm now in the process of moving back to ATX, for the Thermalright HR22 (rumors that it will be out very shortly, or NH-D15 at years end), i have a Fractal Design Define R4 (not windowed) and Arc Midi R2 on my way (still on a boat), and ill test both to see how much Define fares against Arc Midi. I have a theory that i haven't proven yet, is weather a more open case with less restriction allow for more efficient cooling to the point that you can take your fans even lower and maintaining better temps and noise, this is what i trying to test, again just a theory, but since the cases are extremely similar in the inside its going to be fun to do.
Now all that said, i do think the none windowed version might be slightly more quiet, out of having more bitumen and steel should let less noise pass.... its up to you if you find it worth extra $25.
After researching a bit more into the PS, while I'd love to get the Kingwin, it seems the SeaSonic X650 will be about as quiet outside of heavy load, which seams to make it worth saving the $40 there...
Its a nice PSU the X650, and always on Newegg seems to be cheaper, even when the X660 gold was released, they continue to have the 650, i though it was going to get replaced... but still there. Worth mentioning that some people have had issues with Seasonic in terms of coil/whinning, in my personal experience, this hasnt been an issue with a X400 and X660 that i own for more than two years, for me Seasonic still perfect. Kingwin has also had comments of whining/coil, but much less than seasonic, there is no prefect PSU out there, and a lot say its a combination of hardware and even bios settings that makes this and not the PSU alone... but i just bring it up as a warning not to avoid its purchase.
In theory its just the fan, one uses the TY141 (green/grey) and the other uses the TY147 (black/white), to what i read they are the same fan just colors, but initially the first of this fans was the TY140 that differ on the bearing, i think the newer are ball bearing and the old was Sleeve bearing. But cross check this, as when i bought the MACHO there was only the green/grey version, but to me if its the same, i would go with black/white for $2, specially if you have a windowed case that will match the black n white theme of the R4. If you wish to get it cheaper, you can also buy it directly from Nan's Gaming Gear, same reseller as on amazon, here is the link, Macho Rev A (BW) $42.92 free shipping
, also recommended to email them to see whats the difference between two versions, they are the only US autorized reseller of thermalright, and very friendly i might add, i asked them if there will be a black n white version of the silver arrow, the same day they modified to include the option on the page.
