our office wants to build a new server to handle our data, over the last 10 years our data was stored on CDs, DVDs, HDDs but now they want all of it in one place that is attached to the network for everybody in the office to access it. the data is 20TB new data and the rest is old, the important now is to store these 20tb and gradually store the other 30tb over time. so what is the best solution to do ? we thought of getting an hp server and connect it to an external enclosure that either had tape drives or HDDs (we haven;t decided yet) or to get a NAS server and connect it to the hp server. what should we do because this is new for us ...

vague question indeed.
With no experience You should probably go commercial (e.g. Nexenta, EMC, NetAPP).
But if You have the nerve to do it DIY:
Like Dimitri said, Your don't even say if Your data needs to stay hot (or do You?)
If You don't have the ressources for big iron already maybe tape should still be considered strongly.
For storing that much data in a central, accessible, networked location you're talking about a file server, yes. You probably want a server specially designed for use as a NAS server. I'm familiar with the Dells, but all the major OEMs offer them. I'm actually sitting not even one foot away from a Dell NAS server with 24TB RAW disk space, that's expandable by hooking it into disk/storage shelves that you can buy and populate with disks.
Your options for backing up that much data are basically to get a big LTO tape library or get a big disk array. Especially if you're talking about actual backups, with a retention schedule (so it's more than just a second copy of your data), the size of your backup media need to be much larger than the amount of data you're backing up, because you'll be storing multiple copies of most of that data, at least with a traditional backup solution.
Which would be why I don't like traditional backup solutions, and prefer a different approach, below.
I'd get an Avamar. (Warning, they are expensive, and I don't know if there are any competing products with similar functionality at the moment.)
They're a family of disk-to-disk backup systems with deduplication at a file-segment level and a lot of other very nifty, very useful features. I recently replaced a large tape library and several external tape drives with two Avamar nodes (the 2nd just provides an "off-site" location for our backups in the event of a disaster-recovery situation, and for legal compliance).
