PC parts are pretty cheap in the US. Of course, you'll have to pay if you want a high-end PC, but even then you're getting a lot of bang for your buck. My previous (desktop) build cost somewhere around $1400 - that includes the PC itself, monitor, speakers, and various other accessories. This system was a beast in its time. Just recently I upgraded it with a new motherboard, CPU, RAM, and an SSD - basically a whole new system, for about $675. This is a high-end PC - depending on what you want, you can spend a lot less than that.
That's what I'm getting at. 675 USD got you a kick ass desk top, here that would work out at about 62'000 yen. You could build an i5 rig with 4GB of ram, standard HD video chipset (the Intel one) and 500GB HD or 1TB if lucky and maybe, a cheap ass no brand HD monitor. Hardly a kickass system but good enough. My own desktop cost about 600USD has 8GB of RAM and 1TB of HD space (2x 500GB) but just standard Intel HD graphics chip set and onboard audio and that came with no OS and no speakers or monitor. This is pretty much the norm here unless you want cheap unbranded crap that will break soon and be low in quality. I ended up buying a nice 17" full HD acer screen and nice Creative Labs sound system which cost an extra 200 odd dollars.
Well, like I said, I only got part of the system for that. I kept the GPU, PSU, case, HDD, DVD burner, monitor, and speakers from the previous system. Still, for me it amounted to a whole new system. That's the cool thing about desktops - you can upgrade it piece by piece instead of having to buy a whole new system every time. I might get a new GPU next.
Oh you can upgrade a Mac, but you have to pay £2049 for the luxury of being able to get into your own system by buying a Mac Pro
Like i've shown with examples. Most individual part prices are no different in USD when it comes to Yen vs Dollar (Unless i'm reading this wrong. Such as even though in USD it's less money it's still expensive? I'm not sure how the logic in that works but if that's what you are saying..). And can be even less as i've shown with the HDDs. You are ALWAYS going to be wasting your money by buying a pre-built name brand PC. You only ever get your money's worth when you buy a PC from a Botique Builder that specializes in High end stuff. If you have the know how, you are always better off building your own PC. I built my current i7 system (Specs ;798Mhz ram speed = 1596Mhz actual) for about 1100-1400$ in parts 2 years ago and was worth every penny. The only things to bring it to it's knees legitimately are from music production(Which can max out my 6GB of RAM easily. Causing drop outs and stuttering) and games that my GPU isn't powerful enough to run. Most name brand PC's are filled with shit OEM low quality parts.
I did build my own PC, always have I'm just not a PC gamer so powerful graphic cards are not needed so I can save cash that way I guess. Audio is important to me though so a good sound card is a must along with good speed and memory.
Yeah you can save a bit of good money by using Integrated. Especially these days. The Intel HD4000 is not that bad for an integrated chip. It's sure as hell a ton better than IGPs 5-10 years ago. If you do a lot of emulation, a lot of emulator's are mostly CPU intensive rather than GPU intensive(Though many offer options for it and emulators like PCSX2/Dolphin are very GPU dependant so those are exceptions) so you could do fine with integrated.
Man they really didn't care too much about coming out with a good design did they? I seen better custom lids from dell... Dear Sega: WTF bro? some hipsters sell a phone sans screen as a console and you can't even do the same? I'm tired of still "cashing the nostalgia" shit, do something good for a change!
