So, do you want us to put a list together for you?
I charge for that kind of work.
3 hard drives, meaning 3.5" hard drives will limit your cases choices.
nMedia PC is a cheaper knock off of Silverstone, which you have to sell your first born to get.
Rosewill, newegg's private label brand, makes ir remotes, and they are sometimes on sale for $12. Buy the remote, and use the IR dongle fo ruse with your Harmony.
If you want inexpensive, AMD is the way to go. I just put together an AMD quad core desktop for a $100.
Motherboard was $20 AR
Processor was $50
Memory was $25 for 8Gb
Everything else was re-used from the computer it replaced.
Just don't expect to buy everything in one shopping trip, if you want to get deals. Retailers know that people have no patience, and will lower the price on component A in hopes that you will buy Components B and C at full price at the same time.
But things as they go on sale, and you will get your high quality build on a budget.
All prices are after rebates:
nMedia PC cases go on sale for $40 on newegg
Power supplies go on sale for $20 for quality, $5 for cheap
SSD's go on sale for less than $1 per Gb quite often
Hard drives remain high, but are slowly coming back to what they were 2 years ago.
Processors: AMd stopped making socket AM3 processors, so a lot of them are being fire saled, along with motherboards that they go into.
6 TV's in the house on FiOS and we only pay $4.99/month to connect them all!!! Power to the CableCard and WMC7!!!
