Decent Budget Case?

Don't say that you'll replace it later. A bad PSU could seriously damage other components. Just wait until you have the cash and get a CX-430 and a Source 210.

 

well this one is better at cooling.

add 3 of those and place them at the place where you can place it £8,99 a piece
---
this is a total of £62 at max

and you have good cooling specs 6 fans in total (you can place 12 in the intire case) but 6 is also good

 

If you're on a budget, just don't get a case at all.

 

Then just save up money.

I agree with Thanatos Telos.

 

just like the first stages of when google started (lego pc case)

altough it costs 79 pounds, i am sure you can get it A Lot cheaper somehwere else! It's one of the best cases you can get for the money and I got it for 50 euro's. So if you can try to find it somehwere for 40 pounds that would be awsome!

 

that is around €120 for that i can get a very good one that can support lots of fans for cooling:
Spire Sentor 6004

it cost €90 €40 for extra fans (with extra fans you have 10 fans in total)

 

You said you are building entry level system, so why i7 or FX-8320?

 

Update for what? For gaming wise i3, i5, or FX-6xxx is pretty much all you need. Unless you have a specific workload it makes no sense to get i7 or FX-8xxx.

Upper tier only gets you more multithread performance, which is not something gaming cares about. I'm using i7-3770K and that is only because I do x264 encoding 24/7.

 

I3 is imo to weak, but I7 is an overkill. I think OP should go with i5-4670K Haswell.

 

i3 is not weak at all. In fact I started out with i3-2100 (Sandy Bridge i3) and HD6950, a beast in gaming.

In fact, you can game very well with Sandy Bridge Pentium believe it or not. i5 gives gaming a bit boost when it comes to demanding games or MMO.
