Nah. I'm worried that the inrush current will take down the grid each morning

There's a liquid cooler on the CPU with a separate radiator that blows out of the case. Just a few fans otherwise.

Ooooh, that was a low blow. Or maybe it was a fast blow?

That’s more reasonable than I was expecting considering the specs. Or is that just me not having looked at pricing a computer for 3 years and not realising how far we’ve come

I don't think it's outrageous. It's just the premium you pay for fast kit at any given time (the Intel 18 core CPU is about twice as expensive, so it could have been worse.)

I'm very happy with how PI performs under Linux on this beast. Stuff that took hours on my old i7-960 under Windows is now done in minutes.

I don't know that I'll finish images a lot faster but it will be a lot less frustrating!

Yeah the AMD chips are really competitive...for a little more than $400 you can pick up and 8-core Ryzen 7, which from the benchmarks I’ve seen, works out about 2x the performance of my i7-3770.

Sounds like a matrix job.

Probably the most frustrating thing price-wise with these new systems is the RAM cost - it's actually climbed in price, not dropped. And it's easy to spend more than the cost of the CPU and motherboard combined on memory.

Admittedly, I'm talking about having memory at the level Rick has in his machine, but that's the new "norm" for higher end processing, content creation, etc.

Purchasing memory (RAM and flash) for manufacturing at work, typically component level parts but we do use some modules, has been terrible over the past year. Lead times are abysmally long and variable and pricing is all over the place, going everywhere except down. I get the feeling that there's a mix of unpredictable demand (here's a new iPhone - no memory for you now!) and deliberate throttling of production.

I read recently that China was going to start manufacturing their own memory. It will be interesting to see what effect that has...

So it was a component build, or out of the box for the price? The price sounds good for the spec, and the full tower will be a great RAID platform.

The Chinese making memory won't be a big issue. "Secure" Taiwan, "appropriate" the technology to the mainland, upscale! Profit!

No kidding

I've recently found essentially a mini-ITX type case that will _just_ hold a micro-ATX motherboard....

The only problem then is the screen, but I digress

I am thinking I’ll need to upgrade my imaging processing machine, my MacBook Pro does a decent job but what Rick has here looks to be along the lines of what I should be getting price/performance.

I spent a day or two selecting components and paid Umart $99 to assemble it. It seemed like a good deal knowing that I'd spend at least half a day of cursing and spluttering to get it put together

I did check out the iMac Pro specs and pricing as a comparison. It made me feel better about spending a fairly large wad of cash
