Best Steam Machine build for 11 Y/O? (Custom)

[R9 295X2]

Needing a HTPC/Mitx build to make my 11 year old brother a steam machine. For £300 ONLY without a Monitor or any peripherals.
I have 3 versions of a build that i think would be good:

• Build 1: Pentium G3258 w/ Low profile 750Ti in a Silverstone ML03B (Milo)
• Build 2: -------- EDIT: No longer an option
• Build 3: AMD A10 7700k w/ 4GB 2400MHz in a Silverstone ML03B (Milo)

Now i need it cheap as possible with enough performance to play majority of Linux steam games. If you are doing a build then please use a XFX TS 450W which is £27 on Saverstore.

Thanks

Is that running SteamOS or fo you need to include a Windows license?

Edit to add: The new 7670K looks slightly quicker and cheaper than the 7700K.

SteamOS. Also i thought the new 7670k was an A8? Is it still better?

From the table here http://www.anandtech.com/show/9456/a...ng-in-the-gaps yes it looks slightly faster.

However, if you are running a Linux like SteamOS then I would try and aim for the Nvidia card if you can. The Nvidia Linux drivers are a lot faster.

Thanks. I think i'll try get the gigabyte low profile 750 ti

The 750 Ti setup will be a fair bit faster and have better driver support for Linux....which makes it a slam-dunk IMO (and that's before talking about upgrade-ability).

AMD Linux drivers are unfortunately quite infamous, not what you want when building a gaming rig :S

So I have to account for the case in the £300 budget?

I can build something reasonable, but going £60 over budget when you include Case and PSU.

As always, see if you can't find something second hand for cheaper.
