Need advice on building a new rig (second try)

[Hymnody]

Hi all,

Thanks so much for providing the info previous round; I have shortlisted the parts below except for two more components and also some additional info which may affect my choices. Sincerely appreciate your kind attention and patience.

CPU and Mobo: ASRock B85 Killer and i5-4570 @ $357
GPU: ZOTAC GTX750TI 2GB DDR5 @ $208
RAM: PC3 1600 CORSAIR VENGENCE 8GB KIT (4gb*2) @ $114
SSD: CRUCIAL 120GB M500 @ $129
HDD: SEAGATE 2TB 7200rpm @ $108
OS: Windows 7 Home Premium 64bit OEM @ $110
ODD: SAMSUNG 24X DVDRW SATA - OEM @ $21
PSU: I understand this is a very important component and do not want to screw this up.. how much does a 750w costs?
Casing: Not into the looks of the casing, just prefer good ventilation.
Monitor: any recommendation for a 21" or 23" ? (May buy two of it)

Thanks so much for reading!

Here are my additional concerns:
1. My room is slightly hotter than room temperature so the temperature of the computer may be a concern.
2. Intend to use two monitors - most intensive activity is probably dota 2 + movie streaming at the same time. Is my GPU chose able to support my activities ?
3. Fibreoptics modem is in the living room, always been using laptop, so not sure how should I connect to the internet ? Wifi Dongle or any other alternatives ? What should I look out to optimise my 100mbps (wireless on desktop)
4. Any comments on the build above ? Please provide reasons to justify for change like value for money, etc.

Once again thanks so much for reading.

A Superflower HX500 will do for your PSU needs.
I think the Corsair 200R or Fractale Arc Midi are solid considerations for their cost. If you can go higher, a Fractale R4 is great.

1. That doesn't really matter as long as there's unobstructed airflow through your tower. I do rendering almost 24/7 and my room's rather warm too.
2. Your GPU is fine. Dota 2 isn't really heavy.
3. If wired is really not an option, I recommend using a wireless dongle depending on what type of router you're using. If using an N router, an ASUS PCI N53 is a solid choice.
4. I would go for Crucial 8GB ram to save $20, and grab a Crucial MX100 128GB SSD.

There is no need to worry about the computer temps at all, unless you're running it under the sun or something.

If Dota 2 + streaming is the most intensive thing, I'd save money and downgrade both the mobo/cpu. Even the mid range i3 would do fine IMO.

A Corsair CX430M/CX500M @$75 and $95 will suffice. Absolute no need for a 750w for your current setup.

actually your build is quite solid le, except for the Ram can get crucial cheaper and the SSD get a mx100 250GB from amazon ba, cheaper. HDD change to WD blue 1TB. PSU superflower hx500.
