Thanks for all the replies. They are very helpful. I have been reading them at work, but I don’t like to post from work unless I have the time to compose the posts.
Some clarifications based on some of the replies:
[ul]
[li]My price range was based on looking at Lenovo, HP, and Dell off the shelf PCs and figuring that was a reasonable range for the level of PC I wanted. $500, $1,000, $1,500, $2,000, etc. won’t make any difference in my short term or long term finances or lifestyle. That said, I don’t want to spend $1,500 if I can get the features I want for under $1,000.[/li]
[li]A big HD is 1TB or larger. I currently have everything on a 1TB drive with plenty of room to spare, though I have both external USB drives and a 1 TB NAS to offload some of the data.[/li]
[li]I’d like to have a mix of USB 3 and USB 2 ports. The USB 2 for various simple peripherals and the USB 3 for external drives/bandwidth intensive peripherals. I figure 6-8 total.[/li]
[li]I know I can add RAM (been there, done that for both PCs and laptops) and I’ve even built one of my past systems myself. It’s like changing the oil in my car- I know how to do it, but I don’t unless I absolutely have to. Also, at the end of the build, I realized that for a few dollars more, I could have ordered the equivalent system (more or less).[/li]
[li]I don’t game (in fact the last computer game I was heavily into was adventure), but I have this belief that if I buy a little bit towards the high end, the PC will not be obsolete (processor, RAM, etc.) as soon and paying extra for more time until I do this again is worth it to me. [/li]
[li]*I have a laptop. * I travel a decent amount and realized long ago that I didn’t want to carry my entire life around in a laptop bag, particularly in places like China. When I’m home, I prefer everything neat and tidy in a single box. A PC plus a laptop is my preference (realizing that given that I go at least 5 years between PC upgrades this might be the last box this size that I buy. Who knows what the appliance of the future will look like.)[/li][/ul]
Jophiel and scr4: Thanks for suggesting a custom solution and a couple of (I assume) reliable sites. I had a bad experience with a custom build with my second computer (In the heyday of computer fairs filling several fairground buildings, I chose one of the small vendors offering customization, specified my dream machine, and then discovered well after delivery that they had freely substituted cheaper components than I specified). Because of this, I am wary of customizing online. However, I just spent about half an hour playing with the configurator on the Cyberpower site and it was fun. Some questions:
Will liquid cooling require that I do any plumbing or add the coolant or does it show up ready to go?
If I specify an SSD and a HD, how do I make sure the OS and other software (if any) is installed on the right disk?
I realized that I also want a quiet system. Am I better off going with a large power supply (say 600W with a normal load under 300W) or going with smaller power supply sized for modest expansion (I don’t intend to install any high power cards or drives)?
Are the spec’d systems on the sites you linked all capable of dual monitor hookups? I’m used to running dual monitors off of two video outputs (DVI and VGA currently), but have come to understand that modern outputs like HDMI, USB-C, and Displayport can be daisy-chained. What should I spec to make dual monitor set up easiest?
Thanks again everyone for the suggestions. They are definitely changing some of my assumptions for this purchase.
