What do you mean by sixy case? its all opinions some like to look inside their case looking at all the expensive equipment they put into their machine. other like the utilitarien look. other the transformer /cylon look. Me I like the kind like the NZXT and the graphite nice lines plenty of cooling with big fans/alot of fans to move hot air out of the machine. I gave him a machine that will last him a long time. and the machine will tell him if somthing is wrong with it. good parts with good warranties. made by good companies. I will tell everybody to stay away from xtreamegear parts they are just bad parts prone to failing.
I put gave him good parts for a system that is under his limit that moniters itself informs him if somthing is wrong adjusts fans by itsself and tells him if anything is overheating. I gave suggestions for several towers. 2 full 2 mid. Also the system has room for expansion give him a blu ray player. and pretty much made the PC take over the movie player for him. THe system will last him more than a few years. spend alot of money on a good machine and you wont have to replace parts in a couple of years besides a video card. the PSU can be upgraded but I would stay with corsair as their warranties are prettty good same with PNY. THe graphite is a little on the large side for a mid but looks really nice. The full towers are for if he ever decides to expand on the system. NZXT looks alienware to me and seems to be a cheap alternatice without all the pretty lights. its up to him though. telling him to get this and that over intel or AMD blah blah is silly and wrong. I just gave him parts I know work good through personal experience.
exteame gear svck corsair is pretty good. always have a profeshional build it if they screw up its on them they have to replace broken parts for free. And the more power you are not using in the machine means the more in reseve that you know is there if you eveer need it.
I gave suggestions, only, and locations where to start looking. And by sixy case, I mean:
1) Easy to work in. Open layout, not a lot of superflous structure to get in the way of running cables and power feeds efficiently.
2) Not a danger to work in. The Lian Li cases almost universally have rolled edges on -everything-. It takes some serious effort to cut yourself on one of them.
3) Easy access. All the Lian Li cases use thumbscrews, so getting in, changing out a bad power supply, and installing/swapping hard drives tends to be quick and painless.
4) All aluminum construction. Steel frame cases weight a ton. Steel and plastic tend to be tough and fragile, with the plastic panels breaking off if you move the system around much.
5) Multiple fan mounts. The average Lian Li case has at least 2 140cm fan mounts; one in back one if front. Some have a 3rd in the top. The Tower can have up to 6 fan mounts. None of which includes the fan that is part of the power supply.
6) It does -not- come with the computer case equivalent of 'idiot lights'. All you need is the freeware SpeedFan program, and you have full monitoring of all temp sensors in the hardware, you can adjust the fans through software, monitor CPU function, HDD temp and speed, and several other things. A user is far better off =learning= how to tell if their system is in trouble, not depending on faceplate speed controller and idiot light arrangement.
7) If you need a window, you can get one for about $10 more on the case cost, or buy it later.
The OP wasn't asking about enthusiast woody point stuff. It was about what you could get and for how much. If someone doesn't say so, I always suggest the simple mid to full tower with no blinky lights or sculpted plastic whoosles. Not the cheapest but sturdy and stylish in a minimalistic way.
And yes, I would recommend AMD chip and motherboard, for the simple reason that you can get around %90 -percent of the spec function of the nearest Intel part for less than half the cost. And unless you are doing power computing, like rendering or CAD or CG or post, 4 gigs is enough; 8 makes you bullet proof, at least from the perspective of thrashing your swapfile...
