I am building a new Mini-ITX PC, it will be my main PC but I will also be running Plex.tv so it needs a bit of grunt to transcode TV.

So far, I have chosen my motherboard and CPU and have a few cases in mind but I am low on funds and wondering if I can get away with using some older memory

The CPU is a Intel Pentium G3258 Haswell Dual-Core 3.2GHz LGA 1150
The Motherboard is a ASUS Z97I-PLUS LGA 1150 Intel Z97

I am still exploring cases, including

In Win BP655 mini ITX case with IP-S300FF1-0

The memory I am thinking of include those below, I am not going to overclock to begin with I just want to know if DDR3 2400 (PC3 19200) will work OK with the above?


G.SKILL Sniper Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C11D-16GSR

CORSAIR Vengeance Pro 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model CMY16GX3M2A2400C11A

Any other recommendations (that are low cost) are welcome.

Any DDR3 ram faster than 1866 is ram that must be overclocked to run at advertised speeds, usually to 1.65v.
My suggestion is to buy 1.5v ddr3 1866 speed such as G.skil ares:

Faster ram comes with higher latency whic negates the speed advantage.
You are looking at 1-2% differences; not much to worry about.
Here is an article on haswell ram speed scaling:

I would be very careful about such power supplies.
For a attractive small case, check out the lian li cases which will use a conventional ATX psu.
You can buy a very good Seasonic psu for not much.

Or, this Q02 is tiny and includes a good fsp psu...
