Will my old system fit in new case?

Hello community of Tom's hardware, I have one question for you.
As title says, I am planning to buy new computer case as my old one doesn't have side holes for fans and has only 2 places for HDD.
I am planning to get 1 of these two cases:

My specs are:
CPU: Core 2 quad q9550, with cooler http://www.ebay.com/itm/HP-445642-001-DC7800-CMT-CPU-Heatsink-with-Shroud-cooler-/251925835976, it has like heatsinks on it, but cooler is on side, not on the heatsink.

GPU: MSI MD HD6770, with Deepcool's V95 cooler http://www.tippnet.rs/userfiles/image/cooler/DeepCool%20V95.png

Mother board: http://www.game-debate.com/motherboard/index.php?mot_id=1991&motherboard=HP%200AACh

Power supply is HP's 365W stock Power supply, I guess it is standard dimensions?


That would be it, if someone could help it would be amazing, as I can't really do it myself, I mean, I guess it wil fit, but I am not 100% sure.

Also, is there some 3 pin splitter cable for mother board as my mother board has only two 3-pin connectors on it?

THANKS IN ADVANCE!

Your motherboard is ATX size and will fit in either case.

I would select a case with two front intakes of 120mm or better.
Side intakes are disruptive.

Also, a 450w psu is recommended for a 6670

Case fans can always be connected to the molex outputs of the power supply.
If you use a 3 pin splitter, both fans will be controlled in the same way, and you need to cut one of the speed sensing wires to keep fromsending confusing speed signals to the motherboard.

When I buy case I won't have much money to buy new PSU, but can I transfer old one (HP 365W) to a new case?
Also, could you recommend me some replacement for it then, so I can buy it in near future?
I can give you rest of specs. if needed.
I would need some with 2-3 molex, 2 3-pins, at least 4 cables for HDD/optical drives.

Thanks on reply, and I hope you will help me on this also !

I forgot to provide information of my current case which is HP dc7800 convertible minitower, which is actually mid tower approx. 45cm high.
