Besides the grommets, we also have extra rubber material on the inside of each bay:
The daughterboard with the SATA Data/Power connectors can be easily seen (Synology marks the top bay as being HDD1 and the bottom one HDD2:
We can also see nearby the 3-pin fan connector:
By removing only a few screws, we will also have access to the rest of the components; this model is equipped with a single-core 1.2Ghz processor (Marvell 6281) which is only cooled by a small heatsink:
Two Hynix H5TQ2G83CFR memory chips can be spotted which are rated at 1333Mhz and we have a total of 512MB:
A lithium Mitsubishi 3V CR2032 can be also spotted on the board, for retaining CMOS settings:
One extra connector is placed in the corner of the PCB, for communicating with the Power On/Off switch and LED:
The rest of the activity LEDs are SMD and can be found soldered onto the motherboard:
Here is an example of a 3.5’’ drive installed in the primary bay of the NAS:
The LEDs are not very bright, but pleasant to watch when the unit is during operation:

it's modularity with custom scripting, cronjobs and Hybrid Raid make it a worthy dedicated OS server replacement. What my server currently does, I can now mimic 99% of it under the DSM of Synology (tested with one at work):
- file server (duh!)
- print server
- backup to clould storage (amazon glacier default, crashplan+ through custom config)
- backup from clients to server (Acronis backup)
- iTunes media server
- streaming media (live conversion of formats to match client needs)
what I don't know it can do is scheduled automated FTP backups (have a cronjob running now that downloads a backup of the site through ftp, from what I can see, it's not easily done through the GUI... and even command line I didn't immediately see a copy-paste solution... to be investigated )
going to a NAS vs complete OS you do lose a lot of flexibility, in return you get more freedom of troubleshooting through tried&tested plug in modules you just add to your system.
