If you are after efficiency for 24/7 operation, i would only go with Intel motherboards, they have a good track in the past of bieng the most efficient, on micro atx LGA1150 there are two options, Intel BOXDB85FL LGA 1150 Intel B85 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel MotherboardIntel BOXDH87RL LGA 1150 Intel H87 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard
For PSU, if you are looking for the lest power draw, i would go with picoPSU, your system should never even reach 200W, so a picoPSU-160-XT + 192W Adapter Power Kit
should be more than enough, there are other options lower in price and in watts, but you need to find out what you system will consume in load and what other components you will place in over time.
If you don't like picoPSU for whatever reason, and you are looking for a standard ATX PSU, then be sure to check that ML03B has a restriction of 140mm, this will take a lot of good PSU out of the list, like Sesonic X series (most are 160mm), Kingwin LZP and str (most are 170mm), there are some but not that many options, my suggestion is SeaSonic SSR-360GP 360W ATX12V v2.31 80 PLUS GOLD Certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready
(matches 140mm lenght), it has reviewed by SPCR Seasonic G360 PSU: High efficiency & performance, low price
. Should be more than enough for the system you are planning and i like the G series as the fan always runs (quietly in my experience) for setups that will get very little air due to the case design.
According to Silverstone ML03B page
, Limitation of CPU cooler 70mm
, so that takes a lot of coolers out, but the case also has opening on the top, so you might be able to get away close to that height (will depend on how you mount it).
The coolers that i would consider are,
1) Thermalrigth AXP-100
- 58mm height, this would be my personal pick, love the looks, the height and size should fit fine.
2) Scythe Big shuriken SCBSK-1000
- 58mm height, but scythe products are very hard to get for the US, and when they are available most of the time are imported from japan so they are more expensive than what they used to be, but regardless i found a build on the desired case that has a BIG Shuriken SCBSK-1000, i believe its discontinued or replaced by a newer model. SPCR did a couple of reviews that mgiht be worth looking, LGA775 Low Profile Heatsink Roundup
and Scythe Big Shuriken 2 & Reeven Vanxie CPU Coolers
, from this last review, seems the big shuriken 2 is also 58mm height, so im assuming its the replamcent or newer iteration of the same cooler, checking amazon for it, there is one that i believe is the same, Big Shuriken 2 Rev. B SCBSK-2100
For memory, im using on Asus Haswell build, Crucial Ballistix Sport 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Profile Desktop Memory Model BLS4K8G3D1609ES2LX0
, this true low profile memory, half height of what you get on other manufacturers low profile, bearly reaches the tabs of the memory banks. Also is low voltage since you planning on running it 24/7 might make a tiny tiny bit of difference (again not much savings but it will also run cooler at lower voltage). Here is an image so you get an idea into how low height they are,
Fans, the case uses 80mm fans =(, not much experience with those since most cases use 120mm now a days, but if i were to need one the one that would be on my top list would be Noiseblocker NB-Multiframe M8-S1 80mm x 25mm Ultra Silent Fan - 1200 RPM - 6 dBA
, i believe i bought one a couple of years ago, i was going to do a cooling mod to my ROUTER but then the ISP changed it a newer Router and the mod was never done, im going to search for the fan if i find ill run fanXpert2 on it and post you the graph to see how it undervolts on 3pin.
