Case Question

[Bags]

Hey,

Turns out we'll be giving my old computer to my grandparents instead of reusing the case.

So now I need to buy a new case.

My psu: http://www.newegg.com/Product/Produc...scrollFullInfo
My ram: http://www.newegg.com/Product/Produc...82E16820231314
My CPU cooler: http://www.newegg.com/Product/Produc...82E16835233082
My motherboard: http://www.thenerds.net/MSI.MSI_Z68A...FYXrKgodZCOWJQ
CPU: 2500k
GPU: MSI 460gtx
HDD: 2 7200 rpm HDs

Current case dimensions:

L = 18inches
W = 8 inches
H = 16.5

And will I need to buy a new CD rom drive or do cases come with those? Thanks. Haven't ordered a case before. If I need one of those, recommend one of those too.

PS: the computer my dad got for them, but will be returning to give them mine instead, is from best buy, and bought with gift cards. Therefore, if it's possible, we'd like to get a case from them to spend some of the giftcard money. However, they charge tax and won't have as good of selection, so this is not necessary. I'd also like to have the case in hand by next Thursday, so shipping time isn't an issue; I can order online from Tigerdirect or neweegg.

Budget is $60 - 80, might be able to go slightly over, if you can make a strong enough case (heehe) to my dad for me to spend more than that.

Thanks.

Is something like this: http://www.newegg.com/Product/Produc...82E16811129066
