Micro-ATX i5 Gaming/Portable Build ~ $600

[tazdirector]

Alright, after posting here a few weeks ago, I think I've moved from the Phenom to the i5-750 for a new portable system build

Basically, I need to move my system every week between two locations, thus the desire for portability.

It seems like the no-brainer approach is to go with the following for a case:

Thermaltake VF1000BWS Black Aluminum Front Panel/ SECC Chassis MicroATX Desktop Computer Case

As such, my opportunities are limited to MicroATX motherboards (a new venue for me).

In addition, I've picked up a NEW 24" Dell Monitor, so I've got higher requirements for resolution (1920x1200).

Here's my system build right now:

Alright, after some reading, I'm penciling in the following for my new system build:

My only real question mark is the memory now. I'll be doing some air-overclocking on the i5 and due to the mATX case, won't be "shooting for the moon" in terms of OC'ability. So what kind of memory should I look for? Is 1866 good enough or is it overkill? Could I go with 1600 or even lower speed DD3 memory?

Thanks!

1333 with cas 7 lats. Any higher that 1333 doesn't make hardly any diff and the lower lat gives you more OC options.

Perfect. Thanks for the quick answer Sonic!
