more RAM
slots is always better-- because
IF you want to upgrade-- you don't waste what you have already...
That's the thing... there is so MUCH to choose from... but if that Motherboard is getting good reviews (it is) why not ??
Case is a good basic case --for not too much.
The thing you get with more money for cases is-- extra's like pretty finishes, fan controllers-- you can do your own later on.
Coolermaster Centurion 534 Review - Page 4 - Installation and Convenience
That case has side-facing drive bays and plenty of space-- it is not all aluminum (steel frame/interior)-- but unless you go to LAN parties or move it around a lot --who cares.
Plenty of fan-space.
If you don't know the vendor company--google it for complaints--
just in case...
just remember that the people who have problems with a company-- are more likely to post/call/complain-- We have the BBB and resellerratings.com in the US.
Companies are easy to check on--
most are perfectly good -- just check a little first.
