Oh, interesting. "Webblager: [yellow dot] Ej i lager" means it's out of stock tho (with no info on if/when it will be in). Gotta look for the green dots or the yellow ones that have a date that shows when they get them in again.
I'm thinking I'll just give him 10k and let him pay for the rest himself. He currently thinks that he'll have to buy it himself and is willing to spend a bunch on it anyway. Not 10k but with both of us paying for it the budget would still be quite a bit higher. Mom thought it was a good idea and she's pretty much in charge of his money still ;D
If I don't have to change anything due to the cost, is there anything in the (below linked) original build I should change for quality/performance/cost vs. performance/whatever reasons?
Here's a link to the complete first build. He has either one or two big HDDs and an SSD for some special games and Windows. Can't ask him atm. I gave him a sound card last year but really can't remember which one it was and he never got around to installing it. Bah. The memory card reader is news to me so I have no idea what it might be.
He's spending pretty much all his at home time on the computer. Either watching movies, talking to friends or playing. Mostly everything at the same time. At the moment he plays a bunch of MMOs (with GW2 as his main one), AC: Syndicate and Fallout 4.
If the budget is going up, then perhaps consider getting a Skylake processor and motherboard instead. If he's truly adamant about getting an i7 processor, consider getting the i7 6700 (non-K) model since he only seems to care about the i7 badge and isn't tech-savvy enough to be doing any overclocking. A Skylake socket 1151 motherboard comes with support for newer technology like USB 3.1 which may become more useful in the future.
The Edison M should be a very good power supply seeing as it's manufactured by Seasonic, but I'd recommend the EVGA GQ, it's also high quality. The
750 watt model is 990 SEK compared to the Edison's 1190 SEK and
Jonny Guru's review of the 850 watt model found it to be an excellent power supply.
If he won't be using the DVD drive all that much, consider dropping it from the parts list. Not needing a DVD drive also means you could choose the
Fractal Define S for 819 SEK instead, which is largely similar to the Define R5 but lacks optical drive bays and has fewer hard drive bays, but is nearly the same in terms of overall quality and soundproofing and should have slightly better airflow.
I preferably want an SSD and actually made a pc using the pcpartspicker website but it turned out to be only around 30$ lower (120GB SSD and no HDD). And I'm probably going to have to buy windows from the looks of it if I do a custom build. I will use it for a small business. Using custom business apps, Microsoft office, and internet, all simultaneously. I want no slowdown. I might as well buy this if nothing better is available. Do you know if I can install an SSD into this thing in a later date?
Yes, it should handle your work needs just fine. No slowdown is a hard thing to guarantee, that's dependent on several things like what you're doing with the PC and how well you take care of it (not installing all kinds of crapware, etc). An analogy would be that no car company would ever guarantee a car to never break down, especially if the owner treats it like crap and drives it aggressively hard.
Yes, you should be able to install a SSD into that PC, you will likely have to buy a
SATA cable for the SSD, though.
Are there any suggestions on what a fair price for this rig would be?
It'd depend on other factors like what condition it's in, right? Anywhere around $300~500, depending on how it looks and what it runs like, or if some of the parts still have manufacturer's warranty coverage. Sorry for the unhelpful answer, but it's not always clear. Perhaps you can check craigslist or ebay for similar computers and price it accordingly.
How easy is it to transfer an install of Windows 10? If I build a new PC, I'll most likely kick my current pc to a buddy of mine who could make great use for it, but I don't want to give up my access to Windows 10, and certainly don't want to buy it. Would it be easy enough to format this PC, install Windows 7 for him, and transfer 10 over to my new machine?
Is your current license of Windows 10 a result of upgrading from a copy of 7/8/8.1? If yes, is the Windows 7 license you're installing for your friend a whole new license or the one you upgraded from?
