As a computer hardware geek by trade, there are a few considerations when it comes to storing & playing computer data, aside from laptop vs. desktop.
A laptop is a content consumption device, just like an iPad or other similar machine. It is lacking two features that IMO are critical to any computer used for creating or storing your valuable data.
The first is ECC memory. Without ECC memory, memory errors will inevitably end up causing data corruption. This is more pertinent to data creation than to data storage. If you're using this machine to rip the CD's and create the lossless audio files, then you may want ECC memory. ECC memory will detect and correct memory errors automatically, no action required on your part.
The second is RAID-1 mirrored hard drives. Data is stored in 512 byte sectors (4096 byte on the newest models). These sectors inevitably go bad after time. Fortunately, the drive firmware is intelligent enough to relocate unreadable sectors into dedicated reserve space. That keeps the drive running and healthy, but data stored in any unreadable sectors is lost. That results in data corruption for you. A RAID-1 mirror on the other hand, assuming a decent hardware raid controller, (or even better, the software RAID available in Linux) is clever enough to rebuild the data from a bad sector relocation, using the good copy on the other drive. This happens seamlessly and transparently, no action required on your part.
My home audio server has both these things of course. The only downside is that these two features are not typically offered on consumer grade hardware. You need commercial workstation or server hardware. Why the computer manufacturers think that only businesses deserve reliable hardware that is highly resistant to data corruption, but your average consumer does not, is another discussion...
