Hiya Guys! I need your help to look at my new rig and to spot any incompatibities or where I need to change something desperatly!

Ok I'm building this build for gaming (mainly) and heavy multitasking. I would appreciate any modifications/advice you may have regarding the components of the build.

2 Key questions I have also!
1) Is this rig going to fit into the Antex mid p182 case? especially concerned regarding PSU, MOBO and GPU. Is the MOBO truely AM3 compatible? i.e. x4 955 and beyond?
2) First major build... so It may seem newbish but do I need to buy any more cables for the build or will enough come with the items I am buying?

I appreciate any feedback regarding this build!

Thank you for your time!

To answer the Qs:

1. See above on the case. 1a. Yes, as much as any current board will be.
2. No you'll get everything.

One more thing. The 750GB Caviar Black is slower than the 640GB or 1TB. This is because it uses less dense 250GB platters. The 640Gb uses 320GB platters, while the 1TB uses 334GB platters.

It will all fit, but change the CPU cooler to the very quiet Scythe Zipang. It's a good cooler, not as strong as the Akasa but top rated and should be a good fit on the board and in the case.

Okay so I think Im almost sorted!

I've got hold of a little more cash so I can stretch to get a 4870 or a GTX 260 Black Edition. I take it both these cards would be compatible with my chosen MOBO?

If I do get the Scythe SCZP-1000 Zipang is it going to fit in my case? its huge! Also will this cooler cover over the RAM slots or any other other parts of the MOBO i need to install cards/etc to?

Both cards are singly compatible. Using a 4870 would leave you the option of adding a second in crossfire later, as the board supports crossfire.

This is a pretty nice price, and a very good performer:

These cards just dropped dramatically here, so I guess Overclockers is just more on top of things.

Is that so! Awsome, I think I will go with overclockers on this one! Woop woop only 6 hours till I order my new PC!
