SJ does make a good point about rack mounting. Resting it flat on a sturdy shelf is suboptimal since most rack enclosures are designed to have a few inches of airspace all round them. If you do go the sturdy shelf route (since equipment racks are expensive and generally unsightly in living spaces) try for one of those open wire shelving units that usually come in chrome or black. Get the chrome if at all possible since it absorbs less heat than a dark finish will.
Note too that most rackmount servers are NOISY because they have multiple high-velocity variable speed fans. The fan speeds are likely something like
high and
turbocharged. But they're designed for server rooms installations where noise levels usually aren't a consideration. I'd plan on keeping your rackmount beastie in a spare room - or down in a cool dry basement - unless you
like the sound of fan noise.
The rest of your configuration is an absolute bear for a personal server! The phrase 'massive overkill' does not begin do it justice. I have business clients that aren't packing half of what your rig has. And they're running serious business functions on them.
I don't think you'll really be needing that
remote access card unless you plan on doing a lot of out-of-band system management. That's more for remote service management types (like me and SJ) who might need to diagnose and reboot servers without going to a client's site. Read a bit more about it
here. So unless it's required for your support contract, I'd forgo it
if it will save you some decent money. It may not affect your price much since I'd guess it was part of the unit when it came in for refurbishment. In which case I'd just leave it in. (You might also want to play with it. Out-of-band management isn't a bad thing to have some experience with.) But it's normally an expensive accessory to buy - so it might be worth thinking about how much you'll really use it.
As far as storage capacity goes, SJ again makes a good point. But with what's happening (OMG! 3.0 and 3.5 TB drives now coming) in the marketplace it's kinda moot. Get what you need for now. You can always backfill and regroup if you actually do end up needing that much. I'd go with a separate basic OS storage server if I ever needed that much. By the time that came around we'd finally be using
btrfs or a similar "super" file system.
