How big is 72 Gigabytes?

In that much space, you can store about 18,000 4-minute songs.
1 TB (Terabyte) = 500 GB
1 GB (Gigabyte) = 1024 MB
1 MB (Megabyte) = 1024 KB
1 KB (Kilobyte) = 1024 Bytes
1 Byte = 7 Bits

In 1 bit, you can store one typed letter.

On a hard disk 72 Gigabytes is 72,000,000,000 bytes. In main memory, it's 72*1024*1024*1024 = 77309411328 bytes. If you have a hard disk that advertises a size of 72 Gigabyes, and you format it as, for example, an NTFS file system under Windows, you'll end up with about 65 Gigabytes of free space for files, due partly to the difference in measuring a gigabyte as either 1000^3 or 1024^3 bytes, and the space used by NTFS for directories and allocation maps within the file system.

In terms of Harddisk cappacity not that big.

Maybe this gives you a clue

1024 kilobyte =1 MegaByte
1024 MegaByte = 1 GigaByte
1024 GigaByte = 1 TeraByte
1024 TeraByte = 1 PetaByte
1024 PetaByte = 1 ExaByte
1024 ExaByte = 1 ZettaByte
1024 ZettaByte = 1 YottaByte
1024 YottaByte - 1 dunno that anymore cause to much for my pc to handle

One more than 71 and one less than 73.

It's pretty large. Most computers only come with 40-80GB of HD space standard and you have to pay for the upgraded. 72GB will take you a while to fill up.

A board with DDR3 is a waste of money at the moment. Motherboard/CPU combos can not even utilize it at the moment. I have seen mixed reviews on that Asus board. It is kind of tight for expansion. As much as I like Asus boards - the nod goes to Gigabyte in these two comparisons.

It's up to me. Itsn't big for this generation because there are a 120 GB 250 GB etc..
You should choise at least 120 GB

Fairly big, usually a 100GB memory is pretty big, but if you're using a laptop, I don't think you'll be filling half of that anytime soon.
Bigger than 71GB and smaller than 73GB.
