I'm posting this in the HTPC area since I personally think my Mini is my weakest link, but I may well be wrong (forgive me if this needs to be moved to a different forum, I'm new, but have lurked for a while :P). Basically, I'm trying to upgrade my setup, but I don't have the money to do a full revamp at the moment, so I want to upgrade the 'worst' parts. Here's what I have at the moment...
TV: Samsung UN55EH6000 (just upgraded via Black Friday sales, was a Sharp LC-42D64U before)
Receiver: Yamaha RX-V667
Speakers: 2 x Klipsch KF-26 in front, KC-25 in center, old Sony 100W 8" sub
(the 3 Klipsch speakers were also Black Friday upgrades; prior to them, I had some terrible old Sony speakers from a HTIB 12 years ago; the sub is the last remnant of that system)
PC: Early 2009 Mac Mini 3,1 - 2.0GHz Core 2 Duo P7350 - 8GB DDR3 RAM
Accesories: Harmony 900, HDHomeRun for live football (Roll Tide), game systems (really only used for games, all my media is consumed within Plex, Netflix, ripped movies, the HDHomeRun, etc.)
I run Plex (both server and client) via the Mac, the storage is on a Synology DS410 with 4 x 3TB Hitachi drives. As for the fact that it's a 3.1 system, well, it used to be 5.1, but in our current apartment, there's just no way to run cables for surrounds elegantly, and the wife is picky about that kind of thing. However, if anyone knows any wireless surrounds that don't have the usual issues with wireless speakers, I'd be willing to consider them.
So at my current state, I'm thinking that the weakest part is the Mini. The processor is just getting ridiculously outdated, it wasn't even the top of the line one at the time, and I would think putting an SSD in as the drive would improve things drastically, too (the drive that came with it I believe is 5400 rpm). I did just replace the TV and front speakers, but that was more of a "hey, I have old equipment, and here's a good opportunity" thing than anything else. I also would love to go to a different remote setup (the 900 works fine, but it has that annoying delay, even after tweaks/updates), and any other accessories or additions that I could get would also be good, I may just not be aware of what's out there. I'm up for pretty much anything that will either 1) give me more awesome stuff my setup can do or 2) keep the capabilities of the setup the same but reduce the amount of equipment needed to do so.
